How to Compress an Image — Step by Step
1
Upload your image. Click "Choose Image" or drag and drop a JPG, PNG, or WebP file onto the upload area. The file loads instantly inside your browser — nothing is sent to any server.
2
Set your quality level. Drag the Compression Quality slider. A higher value (80–95%) keeps more detail with a moderate size reduction. A lower value (40–70%) achieves maximum savings with minimal visible difference on screen.
3
Choose your output format. WebP delivers the smallest files for modern browsers. JPG is ideal for photographs shared widely. PNG is best when your image has transparency or sharp edges such as logos and screenshots.
4
Click "Compress Image". The tool draws your image to an off-screen canvas and re-encodes it at the quality you chose. A live stats bar shows Original size, Compressed size, and exactly how many bytes you saved.
5
Download your compressed image. Click the Download button to save the result. The filename includes the format so you can easily tell your optimised files apart from the originals.
100% PrivateYour image is never uploaded. All compression runs locally in your browser.

Frequently Asked Questions
Is this image compressor really free? Any hidden limits?
Yes — completely free, no account, no subscription, no watermark, and no hidden file limits. You can compress as many images as you like. Rekreay is supported by advertising, which keeps every tool free for everyone.
Does my image get uploaded to your servers?
No. Compression happens entirely inside your browser using the HTML5 Canvas API. Your file is never sent anywhere. This means your images stay 100% private, and the tool even works offline once the page has loaded.
What quality setting should I use?
For web images and social media, 75–85% is the sweet spot — it typically cuts file size by 60–80% with no visible quality difference on screen. For high-quality prints or archiving, stay above 90%. For thumbnails or quick email attachments, 50–70% works well.
What is the difference between lossy and lossless compression?
Lossy compression (used by JPG and WebP) permanently removes image data that the human eye is unlikely to notice, achieving the largest file size reductions. Lossless compression (used by PNG) shrinks the file without discarding any data — the image is pixel-perfect after decompression. This tool uses lossy re-encoding for JPG and WebP, and lossless for PNG.
Which output format should I choose — WebP, JPG, or PNG?
WebP is the default and recommended choice — it delivers the smallest files at any given quality level and is supported by all modern browsers. Choose JPG if you need broad compatibility (including older software). Choose PNG only if your image has a transparent background, since JPG and WebP do not support transparency.
Is there a maximum file size or image dimension?
There is no fixed limit — it is constrained only by your browser's available memory. Images up to 20–30 MB process without issue on most modern devices. Very large images (50 MB+) may be slower on older hardware, but the tool will not reject them.
