Image Compressor
Large images slow down a page and cost people money on metered connections. This compressor reduces file size in your browser by re-encoding the picture. You trade some visual detail for fewer bytes. Compare the preview before you replace the original, and keep the source file if you still need it for print.
How to use the Image Compressor
- Choose an image. JPEG, PNG, and WebP are the formats you will usually compress for the web. Start with a copy, not your only original.
- Compress and compare. Check edges, text inside the image, and flat colors. If type looks muddy, use a higher quality or a smaller resize.
- Download the smaller file. Note the new size. If the savings are tiny, the file was already compressed and you can keep the original.
When it helps
- Blog and marketing images. A hero photo does not need a 4 MB export. Compress it before you upload it to the CMS.
- Screenshots in docs. UI screenshots are often oversized PNGs. A compressed version is enough for a guide.
Common questions
Will compression ruin the image?
Lossy compression discards detail on purpose. If the preview looks worse than you can accept, keep the original or compress less aggressively.
Is the file uploaded?
No. Compression runs in the browser with a client-side library. The picture is not sent to Toolzy.
Should I compress an SVG here?
SVG is text. Use an SVG optimizer, or convert to PNG with the SVG to PNG tool if you need a bitmap.
Does a smaller file help SEO?
Faster pages are easier to use, and heavy images are a common reason a page feels slow. Compression helps only as part of sensible dimensions and modern formats.
