Which format gives the smallest file?
WebP is usually the smallest and is supported by every modern browser, which makes it the best choice for websites. JPG is ideal for photos you’ll send or print. PNG is for screenshots, logos and graphics with sharp edges or transparency; GrabKit shrinks PNGs by reducing the number of colours, which keeps them crisp.
Quality settings explained
A quality of 70–80% is the sweet spot for most photos: files are often 50–80% smaller and the difference is very hard to spot. Use the comparison slider to check fine details like text and faces. If a compressed file would end up bigger than the original, GrabKit keeps the original instead.
Resizing matters just as much as quality. A 4000-pixel phone photo shown on a website at 1200 pixels wide wastes most of its data, so set a maximum size to shrink it in the same step.
Frequently asked questions
Is the image compressor free?
Yes, completely free. There is no sign-up, no watermark, no daily limit and no premium plan.
Are my images uploaded?
No. GrabKit processes your file with code that runs inside your own browser. The file is never sent to a server, so nobody (including us) can see it. You can even disconnect from the internet after the page loads and the tool keeps working.
Does compression remove metadata?
Yes. Compressed images are re-encoded without EXIF data, which also removes any GPS location.
What’s the best quality setting?
Start at 75%. Go higher for images with fine text or gradients, lower for thumbnails.
Can I compress HEIC photos?
Yes. HEIC photos are converted to JPG or WebP as part of compressing them.
