FILE CONVERTER
Convert images (PNG, JPG, WebP, PDF) and videos (MP4, MOV, AVI, WebM, GIF, MP3) instantly in your browser — nothing uploaded.
// WHY US
SECURE BROWSER-BASED FILE CONVERSION — NO UPLOADS REQUIRED
Most online converters work by uploading your file to a remote server, processing it there, and sending it back. That means your photos, documents, and videos are copied onto servers you don't control — and you're trusting strangers with potentially sensitive content. This converter works differently: every conversion happens entirely in your browser using the Canvas API for images and FFmpeg WebAssembly for video. Your files never travel over the network. No server ever sees them.
Convert MP4, MOV, WebM, and AVI Instantly in Your Browser
Upload any common video format — MP4, MOV, AVI, MKV, WebM, FLV, or M4V — and convert to MP4, WebM, animated GIF, or extract audio as MP3. The no-upload MP4 to GIF converter is especially popular for creating web-ready animations from screen recordings. The MP4 to WebM converter produces smaller files for modern browsers. The MP3 extractor pulls audio from any video without re-encoding the audio stream.
Private PDF to PNG, JPG to WebP, and Image Conversion
Image conversion supports PNG, JPG, WebP, GIF, and BMP as input, with output to JPG, PNG, WebP, or PDF. The private PDF to PNG tool renders your image to a standard A4 page — no upload, no account, no watermark. Use the quality slider on JPG and WebP exports to balance file size against visual fidelity. Transparency is preserved when converting to PNG or WebP; JPG output fills transparent areas with white.
// FAQ
FREQUENTLY ASKED QUESTIONS
Q1.Are my images uploaded to a server?
No. All conversion happens locally in your browser using the Canvas API and JavaScript. Your files never leave your device.
Q2.What formats can I convert?
Images: upload PNG, JPG, WebP, GIF, or BMP — output as JPG, PNG, WebP, or PDF. Videos: upload MP4, MOV, AVI, MKV, WebM, FLV, or M4V — output as MP4, WebM, animated GIF, or MP3 (audio extraction).
Q3.What does the quality slider do?
For JPG and WebP output, the quality slider controls the compression level. Higher quality means larger file size but better image fidelity. PNG uses lossless compression and has no quality setting.
Q4.Why does JPG not support transparency?
The JPG format does not support transparency (alpha channel). When converting a PNG with transparent areas to JPG, those areas are filled with white. Use WebP or PNG if you need to preserve transparency.
Q5.What size is the PDF output?
The image is scaled to fit an A4 page (210×297mm) while maintaining its original aspect ratio, with equal margins on all sides.
Q6.Is there a file size limit?
There is no enforced limit. Images process almost instantly. Video conversion runs via WebAssembly in your browser — larger files (500MB+) may be slow depending on your CPU. The first video conversion also downloads the FFmpeg engine (~30MB), which is then cached for future use.
Q7.How does video conversion work in the browser?
Video conversion uses FFmpeg compiled to WebAssembly (WASM), which runs entirely in your browser. On first use it downloads the ~30MB WASM engine (cached afterward). Your video file never leaves your device — everything is processed locally.
