Why FreeCompressor
Compress images without uploading them anywhere
Private by design
Files are processed with the canvas API on your device. Disconnect from the internet — it still works.
Target size mode
Need “under 100 KB” for a form or email? Pick a target and we automatically choose the output format and quality with the best image quality that fits.
Batch & convert
Compress a whole folder and convert between PNG, JPG and WebP in the same pass.
