Free Online File Conversion & Editing Tools

Online Convert File provides a comprehensive suite of over 30 free tools for converting, compressing, trimming, and transforming files across every major format. Image conversions — including JPG, PNG, WebP, AVIF, BMP, GIF, TIFF, and ICO — run entirely in your browser using the HTML5 Canvas API, meaning your files never leave your device. This makes our image converter one of the most private options available online.

For video, audio, and document conversions, files are securely uploaded to our server over an encrypted HTTPS connection and processed using industry-standard open-source tools: FFmpeg for video and audio processing, and LibreOffice for document format conversion. All uploaded files are stored in isolated temporary directories and automatically deleted within 4 hours — whether the conversion succeeds, fails, or is abandoned.

Beyond file conversion, we offer video editing tools (compress, trim, resize, mute, rotate), PDF tools (merge, split, compress, convert), image editing (resize, compress), developer utilities (JSON formatting, hash generation, Base64, URL encoding), and everyday tools (QR codes, password generator, color picker, word counter). Every tool is completely free, requires no registration, and works on any device with a modern web browser.

Frequently asked questions

Is Online Convert File really free?

Yes, completely free with no hidden costs. All 30+ tools are available without registration, payment, or usage limits.

Are my files private and secure?

Image conversions run 100% in your browser — your files are never uploaded to any server. For video, audio, and document conversions that require server processing, files are uploaded over encrypted HTTPS, processed in isolated directories, and automatically deleted within 4 hours.

Do I need to create an account?

No. All tools work instantly without any registration, email verification, or account creation.

What formats are supported?

We support over 150 format combinations: JPG, PNG, WebP, AVIF, BMP, GIF, TIFF, ICO (images); MP4, WebM, AVI, MOV, MKV (video); MP3, WAV, FLAC, AAC, OGG, M4A (audio); PDF, DOCX, XLSX, PPTX, ODT, CSV, RTF, TXT (documents). Plus video tools for compression, trimming, resolution changes, audio removal, and rotation.

What are the file size limits?

Image conversions have no size limit since they run in your browser. Server-side limits: 2 GB for video tools, 300 MB for audio, 100 MB for documents, and 50 MB for PDF tools.

Can I compress or trim videos?

Yes. Our video tools let you compress videos with an adjustable quality slider, trim clips by setting start and end times, change resolution (4K to 240p), remove audio tracks, and rotate or flip videos. Trimming and muting use stream copy for instant, lossless processing.

Does it work on mobile devices?

Yes. All tools are fully responsive and work on any modern browser — Chrome, Firefox, Safari, Edge on Windows, macOS, Linux, iOS, and Android.

How is this different from other converters?

Our image tools run entirely in your browser — no upload, no queue, no file size limits. Server-side tools use professional-grade open-source software (FFmpeg, LibreOffice) with real-time progress tracking. Everything is free with no premium upsells, no watermarks, and no registration walls.
