Is the compressor really free?

Yes, completely free with no limit on the number of compressions. No subscriptions, no premium plans, no trial. The service is supported by discrete advertising. If you prefer to refuse personalization cookies, you still have access to everything.

Compressed files stay temporarily on the server, at a random, unlisted address, so you can download them again, and are automatically deleted after 30 days — or immediately if you click × or “Clear”. The originals are processed and discarded immediately after compression.

Which formats can I compress?

We support 15+ formats: JPEG, PNG, WebP, GIF, BMP, TIFF, ICO, AVIF, HEIC, PDF, SVG, PSD, TGA, PCX, XPM, DDS. See the full formats page.

Does it work on mobile?

Yes, optimized for iPhone, Android, iPad and any tablet. Tap the upload area, pick the file, choose the format, download.

Does compression add a watermark?

No. Compressed images come out clean — no watermarks, no overlay text. Quality only drops according to the compression level you choose.

Compress images for websites and blogs.

Heavy images are one of the main causes of slow websites. Google uses loading time as a ranking factor. Optimized images improve LCP (Largest Contentful Paint), one of the Core Web Vitals that can affect your position in search results.

WebP compresses 25-35% better than JPEG at equivalent quality, ideal for WordPress and Webflow.

For hero images, stay under 200 KB. For blog thumbnails, 50-80 KB is enough.

Use the Size KB mode to set an exact target: the compressor adjusts the quality automatically.
