PixConvert: Private Browser-Based Image Converter

Online image converters upload your files to remote servers. That's slow, raises privacy concerns, and often comes with file size limits, watermarks, or forced signups. People just want to convert an image quickly without jumping through hoops.

I built PixConvert — a free image conversion tool that runs 100% in the browser. No uploads, no servers, no signup. Your files never leave your device.

HEIC, JPEG, PNG, WebP, AVIF, TIFF, GIF, BMP, SVG, and ICO — 14 different conversion combinations covering everything from iPhone HEIC photos to next-gen web formats.

100% private — all processing happens locally in the browser using client-side APIs. Zero server uploads.

No signup required — open the page and start converting immediately

Works offline — after the first load, the entire engine runs without internet

Batch processing — convert multiple images at once and download individually or as a ZIP archive

Drag & drop — simple file selection with drag-and-drop support

Files up to 50 MB — generous limit for a browser-based tool
