Why use this image converter?
- No upload, private by design: conversion runs in your browser with WebAssembly. Your images are not sent to a server, which keeps it fast and private.
- Truly bulk: drop hundreds of files or a whole folder; they are converted in parallel on multi-core CPUs and downloaded as a single ZIP.
- Real encoders: MozJPEG for JPG, native encoders for WebP and AVIF, oxipng for PNG; a target file size (for example “at most 200 KB”) is found automatically.
- Full control: quality, resizing, rotation, cropping, watermark and file-name templates, with per-file format and settings.
- Clean output: metadata such as GPS location and camera details (EXIF) is always removed.
Supported formats
Add JPG, PNG, WebP, AVIF, GIF, BMP, SVG and ICO files; export to JPG, PNG, WebP, AVIF, GIF, BMP, ICO, PDF or a favicon pack.
