Open a picture and it is compressed immediately, with the result shown side by side as numbers: original size, new size, and how many percent you saved. Move the quality slider and the preview updates live, showing the actually compressed image, so what you see is exactly what you download. Everything runs in your browser; even a 12 megapixel photo compresses in moments.
Need an image under a specific limit for a web form, application portal or email? Switch to Target size, type the limit or tap a preset like 20 KB, 30 KB, 50 KB, 100 KB, 1 MB or 2 MB, and the tool finds the best quality that fits under it automatically. When the target is very small for a very large photo, the dimensions are scaled down just enough to make it.
The most common limits also have their own pages that open with the target already set: compress image to 20 KB, 30 KB, 50 KB, 100 KB, 200 KB, 500 KB, 1 MB or 2 MB, with every cap from 5 KB up in the full compressor collection. Drop a photo on any of them and the compliant file is one click away.
Many compressors show you the untouched original while quietly encoding something worse. Here the preview is decoded from the very bytes you will download, compression artifacts included, so you can judge the quality honestly before saving. The size card always shows the real output size, not an estimate.
The download button lets you pick the output format. JPG is the default for every upload, PNG included, because it is what actually shrinks pictures and what upload forms expect. WebP is usually 25 to 35 percent smaller than JPG at the same quality. PNG stays lossless and pixel perfect for logos and graphics; pick it on the download button when transparency or exact pixels matter more than size.
Your image never leaves your device: reading, compressing and saving all happen inside your browser. No upload, no queue, no account, no watermark. Close the tab and nothing of your picture remains anywhere.
Switch to Target size, enter 100 KB or tap the preset, and the tool automatically finds the highest quality that fits under the limit. If the photo is too large for the target even at low quality, its dimensions are reduced just enough to fit under it.
JPG and WebP are lossy, so some detail is traded for size; at quality 70 to 85 the difference is usually invisible. The preview always shows the actually compressed result, so you can judge for yourself before downloading. PNG output is lossless and never loses quality.
WebP almost always wins, coming out 25 to 35 percent smaller than JPG at comparable quality. JPG is the most compatible choice for photos. PNG is only for graphics that must stay pixel perfect, since it is lossless and therefore larger for photographs.
Because JPG is what actually compresses. PNG is a lossless format with no quality dial, so re-encoding it barely shrinks it, while the same picture as a JPG is often 80 to 95 percent smaller. If you need a real PNG, for transparency or pixel perfect graphics, pick PNG on the download button.
No. The image is opened, compressed and saved entirely in your browser. Nothing is transmitted to any server, which also makes the tool fast: there is no upload or download wait.
