Professional encoders, not a wrapper
libvips for images, ffmpeg for audio and video, LibreOffice for office documents and Poppler for PDF rendering — the same tools that run in production media pipelines, with their real settings exposed.

Convert any file in seconds
Documents, images, video, audio and archives — converted on our servers with professional encoders, then deleted automatically. No watermarks, no software to install.

Features
Built to be dependable
The details that decide whether a conversion tool is usable at work, rather than something you fight for ten minutes and abandon.
Content verification
Every upload is identified by its magic bytes and checked against its extension, so a renamed or malformed file is rejected before it reaches an encoder.
Automatic deletion
Source files are removed the moment a conversion finishes and outputs are purged on a schedule. Nothing lingers.
Metadata stripping
EXIF data — including GPS coordinates and camera serial numbers — is removed from images by default. Keep it with one switch when you need it.
Batch processing
Queue multiple files with one output format and settings. Each reports its own progress and can be cancelled independently.
Real encoding controls
Quality, resolution, bitrate, sample rate, frame rate, DPI and compression level — tuned defaults, adjustable the moment they matter.
Signed downloads
Links are short-lived and cryptographically bound to a single conversion, so they cannot be guessed, enumerated or replayed.
Live progress
Conversions report real encoder progress, not a fake spinner, and long jobs can be stopped mid-run.
Runs anywhere
One container, a PostgreSQL database and any S3-compatible bucket. Self-host it on your own infrastructure if you prefer.
Supported formats
270 conversions, all first-class
Not a wrapper around one tool. Each category is handled by the encoder built for it, with settings you can actually reach.
Convert images without losing quality
Transcode between JPEG, PNG, WebP, AVIF, TIFF and GIF, resize in the same pass and strip location metadata automatically.

How it works
Three steps, no account needed
There is nothing to sign up for. Every feature and every limit is the same for everyone who opens the page.
- 1
Upload your file
Drag a file in or pick it from your device. Uploads stream straight to storage and the contents are verified against the file signature before anything runs.
Verified before a single byte is stored
- 2
Choose the output
Pick a target format and, if you want, adjust quality, resolution, bitrate or compression. Sensible defaults are already selected.
Only the settings your target format honours
- 3
Download the result
Conversion happens on our servers with live progress. Download with a signed link, then the file is deleted on schedule.
Signed link, minutes-long expiry
Why HexaConverter
Everything free converters get wrong
Most online converters trade your privacy, your quality or your patience for convenience. This one was built to avoid all three.
270
conversion routes
Across images, documents, spreadsheets, presentations, audio, video and archives — every one declared in a single registry that also drives our validation.
0
watermarks, ever
Output contains exactly what the encoder produced. No branding, no overlays, no injected metadata.
168h
file retention
Source files are deleted the moment a conversion finishes. Outputs are purged automatically after 168 hours, or sooner if you delete them yourself.
10 GB
per file, free
Convert immediately. No signup wall, no paid tier and no account — the same limits apply to everyone.
What you getUsTypical
- No watermark on output
- Files deleted on a schedule, not "eventually"
- EXIF and GPS stripped by default
- Real encoder settings exposed
- Live progress from the encoder itself
- Honest error messages when a file fails
- No ads or tracking scripts
- Self-hostable on your own infrastructure
“Typical” describes common practice among free online converters, not any single named product. Verify ours on the privacy policy and FAQ.
Why you can trust it
Claims you can check yourself
HexaConverter is new, so there are no customer quotes here yet — we would rather show you 270 verifiable conversions across 43 formats than testimonials you have no way to confirm.
Every route is declared, not implied
One registry defines each supported conversion. The picker, the API and the validator all read from it, so the platform cannot advertise something it will not do.
Inspect /api/formats →Uploads are verified byte-by-byte
Files are identified by their magic number and matched against the declared extension before a single byte is stored. Rename a PNG to .pdf and the upload is refused.
How we handle files →Deletion is scheduled, not promised
Source files go the moment a conversion finishes. Outputs are purged by a cron job after 168 hours — the same for everyone.
Read the retention table →No watermark, no upsell wall
Every conversion produces exactly what the encoder emitted. There is no degraded output, no queue penalty and no interstitial between you and your file.
See what is supported →Self-hostable
One container, PostgreSQL and any S3-compatible bucket. If you would rather not send files to someone else at all, run the whole platform yourself.
Deployment guide →Five converters, one platform
Each converter uses the encoder best suited to the format — libvips for images, ffmpeg for media, LibreOffice for office documents.
