Private File Converter

Convert files without handing them to anyone. The work happens on your device, so your files are never uploaded, stored or shared.

Accepts: images (PNG, JPG, WebP, GIF, BMP, SVG, ICO, AVIF, HEIC), PDF, Word (.docx), Markdown, HTML, TXT, spreadsheets (XLSX, XLS, ODS, CSV, TSV), JSON, XML, YAML, and video (MP4, MOV, WebM, MKV) or audio. Video can become GIF (first 15 seconds), WebM or MP4 (recorded in real time, so it takes as long as the video), a still image, or just the audio. Mixed batches are fine.

What private means here

Your files are read and converted in your browser and never sent to a server. We do not ask for an account, an email address or any personal information. The only thing saved in your browser is your colour theme.

Good for sensitive files

Contracts, scans of IDs, medical letters, financial exports and personal photos are exactly the files you should not upload to a random website. Converting them locally avoids that.

What you can convert

Images (PNG, JPG, WebP, GIF, BMP, TIFF, ICO, SVG, HEIC, AVIF), PDF, Word (DOCX), Markdown, HTML, TXT, spreadsheets (XLSX, XLS, ODS, CSV, TSV), JSON, XML, YAML, audio (MP3, WAV) and video (MP4, WebM, GIF).

Frequently asked questions

Are my files uploaded anywhere?

No. Conversion happens inside your browser. Your files are not sent to us or to any other server.

What do the ad and analytics providers see?

Ad and performance-measurement providers load with the page and can receive technical details such as your IP address. They never receive your files. See the privacy policy at the bottom of the page.

Is there a file size limit?

We do not set one. The only limit is your device's memory, so for very large batches work in several groups.

Your files stay on your device

All conversions happen inside your browser. The files you add are never uploaded to our servers, and we cannot see them, store them or share them. Closing or reloading the page discards them.

What we collect

We do not ask for accounts, names or email addresses, and we do not collect personal information ourselves. The only thing saved in your browser is your chosen theme (white, dark grey or black), kept in local storage so it is remembered next time. You can clear it in your browser settings.

Third-party services

Advertising. The ad at the top of the page is provided by A-ADS, and other ad networks may be added. Ad providers can receive technical information such as your IP address and browser details, and may use cookies or similar technology. See each provider's own privacy policy for details.

Hosting and libraries. This site is served by a hosting provider, which receives standard server logs such as your IP address. When you use a conversion that needs a helper library, your browser downloads it from cdnjs (Cloudflare) or jsDelivr, which can see your IP address as part of that request.

Tips

The crypto addresses in the footer are public. Tips are sent through the Solana and Base blockchains, which are public. We do not collect any information about you when you send one.

Children

This site is not directed at children under 13, and we do not knowingly collect information from them.

Changes

We may update this policy and will change the date above when we do.
