Why You Should Compress Images

Uncompressed images are the #1 cause of slow websites. A typical smartphone photo is 3–8MB. A well-compressed version of the same photo can be under 400KB — with no visible difference on screen. That 90% size reduction means your pages load 10× faster.

JPG vs PNG vs WebP — Which Format Is Smallest?

WebP is 25–35% smaller than JPG at the same quality. It's supported in all modern browsers (Chrome, Safari 14+, Firefox, Edge). If you're uploading to a website, convert your JPGs to WebP using the WebP Converter.

PNG is best for images with transparency or sharp edges (logos, icons). It compresses losslessly — meaning no quality reduction but larger files than JPG. If you don't need transparency, convert PNG to JPG first.

JPG is the universal format — works everywhere, compresses well, and is the best choice for photos.

FAQ

Can I compress multiple images at once?

Currently the tool processes one image at a time. For bulk compression, process each image separately.

Does compressing affect the image resolution?

No — compression reduces file size by removing redundant color data, not by reducing resolution. Your image stays at the same pixel dimensions.

Is there a file size limit?

Standard images up to 20MB are supported. Most JPGs from phones are well within this limit.

Can I compress PNG files?

Yes — the compressor handles JPG, PNG, and WebP. PNG compression is lossless to preserve transparency and sharp edges.
