Is it safe to upload images?

Yes, absolutely safe. All processing happens locally in your browser. Files are not transferred to our servers and are automatically deleted after compression.

How much can file size be reduced?

Compression level depends on format: JPG — up to 90%, PNG — up to 70%, WebP — up to 50%, GIF — up to 70%, SVG — up to 70%. Image quality remains acceptable.

Can multiple files be compressed simultaneously?

Currently the service processes one file at a time. This ensures maximum processing quality and control over each image settings.

What's the maximum file size?

Maximum uploadable file size is 50 MB. For larger files, we recommend reducing resolution first.
