About

A file converter that never sees your files.

saveas.now turns photos, videos, audio, documents, PDFs and archives into the formats you need, and cleans up spreadsheets of any size. The whole job runs inside your browser. There is no upload step, so there is nothing to wait for, nothing to trust us with, and nothing to delete afterwards.

How it works

  1. 1Drop a fileDrag it in, pick it, or paste it. The page reads the first bytes to work out what it really is; the extension is not trusted.
  2. 2Take the suggestionYou get the output a professional would pick, with one line saying why, and a More options link if you disagree.
  3. 3SaveThe result streams straight to a location you choose. Big videos never sit in memory.

Why nothing is uploaded. The converters are compiled to WebAssembly, the same technology that runs games and video editors in a browser tab. When you drop a file, your browser downloads the converter it needs, once, and runs it on your machine. The server only hands out the page. Open your browser's Network tab during a conversion and watch: nothing but the page itself goes anywhere.

Everything it converts

Grouped by the kind of file you start with. Which outputs a particular file gets depends on what is inside it and what this browser can encode; the page says so when something is missing.

Images

Photos and graphics to the modern web formats, favicons and PDF, with resizing and privacy-safe metadata.

HEIC / HEIF (iPhone photos)
  • JPEG
  • WebP
  • PNG
  • PDF
JPEG first, because it opens everywhere HEIC does not.
JPEG
  • WebP
  • AVIF
  • Optimized JPEG
  • PNG
  • PDF
Optimized JPEG re-encodes with mozjpeg, usually 20 to 30 percent smaller with no visible change.
PNG
  • WebP
  • AVIF
  • Optimized PNG
  • JPEG
  • Favicon (ICO)
  • PDF
Transparency and hard edges are kept losslessly; the favicon appears for square-ish images.
WebP, GIF, BMP, AVIF
  • JPEG
  • PNG
  • WebP
  • AVIF
  • PDF
TIFF
  • JPEG
  • PNG
  • WebP
  • AVIF
  • PDF
Photoshop (.psd, .psb)
  • PNG
  • WebP
  • JPEG
  • AVIF
  • PDF
The flattened picture as last saved in Photoshop. Layers, text and effects are not re-rendered; transparency is kept.
SVG
  • PNG
  • Favicon (ICO)
  • WebP
Rendered at the size you choose; height follows the aspect ratio.
Animated GIF or WebP
  • MP4 (silent)
  • GIF
The MP4 is a fraction of the size and loops in most players.
Options
  • Longest side (resize)
  • Quality, or lossless
  • Keep camera data (EXIF) for JPEG sources, off by default; location is always removed
  • PDF page: same size as the image, A4 or Letter
Good to know
  • Metadata is stripped by construction. Nothing carries over unless you turn on Keep camera data, and GPS never does.
  • AVIF is slow on very large images and some older software cannot open it.
  • JPEG has no transparency; see-through areas become white.
  • Photoshop files in CMYK, Lab or 16-bit colour are not read yet; save a copy in 8-bit RGB first.

Video

Anything to MP4 that plays everywhere, the soundtrack on its own, or a short GIF, with trim and downscale.

MP4, MOV, MKV, WebM
  • MP4 (H.264 + AAC)
  • WebM (VP9 or AV1)
  • Audio only (M4A)
  • GIF
A file that is already H.264 with AAC is repackaged without re-encoding, which is fast and loses nothing.
iPhone and other HEVC (H.265) video
  • MP4 (H.264 + AAC)
  • Audio only (M4A)
  • Audio only (MP3)
Where this browser can't decode HEVC itself, a bundled decoder does it in software; Safari and machines with hardware HEVC are faster.
AVI, WMV / ASF, FLV, MPEG-PS / TS, RealMedia
  • MP4 (H.264 + AAC)
  • Audio only (M4A)
  • Audio only (MP3)
The slow path: a bundled decoder reads every frame in software, then the normal encoder takes over. Expect real time or slower.
Options
  • Resolution: same as source (up to 4K), 1080p, 720p or 480p
  • Trim start and end
  • GIF width and frames per second
Good to know
  • Outputs this browser can't make, such as WebM without a hardware VP9 or AV1 encoder, stay on the list greyed out, with the browser that can.
  • A video codec nothing here can decode is named, with the browser that can.
  • GIF is offered for clips of 15 seconds or less; anything longer makes absurd files.
  • Without a hardware H.264 encoder the page shows a time estimate before you start.

Audio

Lossless masters to small files, small files to whatever a device demands, with trim.

WAV, AIFF, FLAC
  • M4A (AAC)
  • MP3
  • FLAC
  • OGG (Opus)
  • WAV
256 kbps AAC is indistinguishable from the original for almost everyone at about a fifth the size.
MP3, M4A / AAC, OGG (Opus or Vorbis)
  • M4A (AAC)
  • MP3
  • OGG (Opus)
  • FLAC
  • WAV
Re-encoding a lossy file loses a little more; the page says so and never offers the same format again except to trim.
Options
  • Bitrate
  • Trim start and end
Good to know
  • FLAC or WAV made from a lossy source gains no quality; it is only a bigger file, and the page tells you.
  • OGG (Opus) needs a browser with an Opus encoder; where it's missing the option is shown greyed out. M4A, MP3 and FLAC work in every browser.

Audio effects

Change how a file sounds, not just its format: loudness, tone and width, saved as WAV or a smaller format.

Any audio file (WAV, AIFF, FLAC, MP3, M4A, OGG)
  • Normalized loudness (−14/−16/−23 LUFS)
  • Limiter (louder, no clipping)
  • Compressor (evens out the volume)
  • Equalized (bass, mids, treble)
  • Bass boost
  • Wider stereo
  • Warmth (saturation)
Every chain ends in a limiter, so a boost can never clip; the output length matches the input to the sample.
Options
  • Effect strength (boost dB, EQ bands, width, amount)
  • Loudness target
  • Output format: WAV (default), FLAC, MP3, M4A, OGG
Good to know
  • Wider stereo needs a genuinely stereo file; the option doesn't appear for mono.
  • Surround (more than two channels) isn't supported; make a stereo version first.
  • Normalize decodes the file twice — once to measure, once to process — so it takes about twice as long as the other effects.

Documents

Office files, ebooks and PDFs to Markdown, HTML and Word; Markdown back to Word or PDF.

Word (.doc, .docx)
  • Markdown
  • HTML
  • PDF
Headings, lists, links, tables and footnotes survive; page layout, comments and tracked changes are dropped.
PowerPoint, Excel, OpenDocument text / spreadsheet / presentation, RTF, EPUB
  • Markdown
  • HTML
  • Word (DOCX)
  • PDF
Each spreadsheet sheet becomes a table.
Markdown, plain text
  • Word (DOCX)
  • HTML
  • PDF
Headings, lists, tables, code and links become native Word styles.
PDF with a text layer
  • Markdown
  • Plain text
  • Word (DOCX)
  • Page images (PNG)
Text comes from the PDF's own text layer; columns are best effort.
Options
  • Page image resolution: 96, 150 or 300 dpi
Good to know
  • PDF output uses your browser's print dialog, where Save as PDF is one click. No file is produced until you choose it.
  • A scanned PDF has no text layer. The page says so and offers page images instead; OCR is on the roadmap.

PDF tools

Make, combine, split, rotate, compress and password-protect PDFs without a PDF app.

One image
  • One-page PDF
Photos are embedded as JPEG at full resolution, graphics losslessly.
Several images or several PDFs
  • One combined PDF
Joined in the order they were dropped.
Any PDF
  • Compress (keeps text)
  • Split into one-page PDFs
  • Extract pages
  • Rotate
  • Shrink
  • Page images (PNG)
  • Protect with a password
Compress re-encodes the pictures inside and repacks the file; text, links and layout are untouched. Split, extract and rotate keep text selectable too. Shrink is the heavier option that turns pages into pictures to cut scans down hard.
Password-protected PDF
  • Unlock (remove the password)
You need the current password; nothing else is changed.
Options
  • Page ranges such as 1-3, 7, 10-
  • Rotation angle
  • Picture size and quality for Compress
  • Shrink resolution and JPEG quality
  • Password to open, and an optional owner password, for Protect
Good to know
  • Shrink makes text unselectable, so use it for sharing, not for archiving.
  • Compress leaves pictures with transparency or unusual colour alone, so a file with only those may not get smaller; it then says so and keeps the original.

Archives

Unpack almost any archive into a folder you choose, with or without a password, turn one archive into another, or zip a set of files.

ZIP, including password-protected ones
  • Extracted folder
  • ZIP with password
  • tar.gz
Streams entry by entry, so large archives do not have to fit in memory; a ZIP with a password asks for it first.
RAR, 7z, tar, gzip, bzip2, xz, zstd, lzip, cpio, ISO
  • Extracted folder
  • ZIP
  • ZIP with password
  • tar.gz
Unpacked in memory and repacked in one step; very large archives may not fit.
Two or more files of any kind
  • ZIP
  • ZIP with password
Streamed to disk as it is built; the password protects every file with AES-256.
Options
  • Password for a protected ZIP, in or out
Good to know
  • Password-protected RAR and 7z archives can't be opened yet; password-protected ZIPs can, whichever tool made them.
  • Where the browser has no folder picker, extracted files download one by one.
  • Entries that try to escape their folder (path traversal) are skipped.

Data

For ops and finance people: open the CSV or Excel export that crashes Excel, clean it up with visual steps or SQL, and export it. Payroll and customer lists never leave your machine.

CSV, TSV, JSON lines, Parquet, Excel (.xlsx)
  • CSV
  • Excel (.xlsx)
  • Parquet
  • JSON
Files load into an analytical engine in your browser rather than into the page, so a few hundred megabytes is fine.
What you can do
  • Filter, sort, dedupe (exact or by key)
  • Select and rename columns, derive new ones
  • Join two tables (inner, left or anti) with a match-rate preview
  • Group and aggregate
  • SQL for anything the steps do not cover
  • Save a list of steps as a recipe and re-run it on another file
Good to know
  • Tables stay in this browser between visits, in private storage, until you clear them.
  • Excel export stops at Excel's row limit and says so.
  • Files of a few hundred megabytes work on a desktop browser with a few gigabytes of memory; Chrome and Edge are the safest.
Open the Data workspace

Two or more files waiting on the home page also get batch buttons: convert them all to the same format, combine them into one PDF, or zip them.

Free and paid

Processing costs nothing per file, so no tier is about quotas. You pay for capability and convenience. Unlocking is an email link, no password. Prices are on the pricing page; checkout opens at launch.

Browsers

Everything is feature-detected, so the page offers only what your browser can actually do, and says why when something is missing.

  • Chrome and Edge on a desktopEverythingResults stream straight to disk, video uses the machine's hardware encoders, and the Data workspace has private storage.
  • Firefox on a desktopMost thingsResults download when finished rather than streaming; very large files can be slow.
  • SafariMost thingsSame as Firefox. Some video codecs are not available for decoding.
  • Phones and tabletsSmall filesMemory is the limit. For big files, use a desktop browser.

Privacy, in one paragraph

Your files, their names and their contents never leave your computer. The only thing the site records about a conversion is a usage event with the file's category (photo, video, spreadsheet) and a size bucket, so we know which converters matter and how big real files are. The event format is strict and cannot carry a name, a hash or a value. Tables in the Data workspace live in your browser's private storage and are gone when you clear them. Unlocking with email stores your address and the browsers you have unlocked, nothing else.

A full privacy policy and terms of service are being written for launch. Questions go through the contact page.

Questions

Is my file really not uploaded?
Correct. The page downloads the converter code to your browser and runs it there. Your file is read from disk by your browser, processed in memory, and written back to disk. Open your browser's Network tab during a conversion: the only traffic is the page itself and a small usage event that carries a file category and a size bucket, never a name, never contents.
Why does a big video take a while?
Because your computer is doing the work, not a server farm. Most of the time that is fast: modern browsers use the machine's hardware video encoder. When there is no hardware encoder for a format, the page shows an estimate before you start and lets you cancel at any point.
Does it work offline?
Yes, once the parts you use have been loaded once. The site can be installed like an app, and a conversion you have done before works with the network off.
What does unlocking with email do?
It raises the daily file allowance, lets you change settings on a conversion, and turns on the Data workspace's transform and export tools. No password; a link is sent to your email and opens the site on that device.
What is Pro for?
Unlimited files and sizes, several files at once, every setting, joins, unlimited export and saved recipes in the Data workspace, and the same license on up to 5 browsers. Pricing is about capability, never about quotas on processing that costs nothing: $39 year pass, $9 30-day pass, $79 buy once. Checkout opens at launch.
What happens to metadata in photos?
It is removed unless you ask to keep it. For JPEG sources there is a Keep camera data switch that copies date, camera and exposure into the output; location is removed either way.
