About File Converter
File Converter made simple
File Converter lets you choose the output format after you upload a file, so one page covers several conversions. Pick the target that matches where the file will be used: widely compatible formats for sharing, lossless formats for editing and archiving.
Why choose File Converter?
What this tool offers, based on how it actually works.
Quick to start
Small files are often done in seconds; larger files and server-side conversions take longer depending on size and current load.
Secure & private
Files travel over HTTPS. Anything uploaded to our servers is removed by an automated cleanup job; some conversions never leave your browser.
High quality output
We aim to preserve clarity and layout, but results depend on the formats involved. See the notes on this page for what to expect.
No installs needed
Use it straight from your web browser; there is nothing to install.
Works everywhere
Desktop, tablet, or mobile—use the same workflow on any device.
Free to use
Start converting for free with no account. Paid plans raise limits; see the Pricing page.

Points that apply to every conversion on this page.

Converting between lossy formats (such as JPG or MP3) and lossless ones cannot restore quality that has already been discarded.
02
Some conversions are approximate: layout, fonts, animation or transparency may not survive in the target format.

What to expect
No installs and no sign-in to get started. Your original file is never modified; you download a new converted copy.
Private by design
Depending on the formats you choose, the conversion runs in your browser (small JPG, PNG and WebP images) or on ToolzStack servers. Uploaded files travel over HTTPS and are deleted afterwards by an automated cleanup job; see the Privacy Policy for the current retention period.

FAQs for File Converter
Common answers so you can keep moving.
Which files can I use with File Converter?
The upload area shows which file types are accepted. If a file is rejected, check that its extension matches its real type; renaming a file does not convert it.
Is my file uploaded?
Small JPG, PNG and WebP conversions can run in your browser; most other conversions are processed on our servers and the file is deleted afterwards by an automated cleanup job.
The conversion failed or never finished
Check that the file opens correctly on your device and is not password protected or corrupted, then try again. Very large files can fail on slow connections; try a smaller file or a different browser.
The result looks different from the original
Different formats store different features. Check whether the target format supports what you used (transparency, animation, fonts) and choose another format if it does not.
