How to compress an image
Drop your image into the box above. It opens locally in your browser tab — nothing is uploaded. JPG, PNG, WebP, GIF, and BMP are accepted.
Drag the quality slider left. The preview shows the live effect on your photo, and the size readout shows exactly how small the file will get. 70–80% is the classic sweet spot: most photos become 3–5× smaller with no visible difference.
Pick the export format — JPG for photos, PNG for graphics with transparency, WebP for the smallest file. Then click Compress & Download. Your original file is never touched.
Frequently asked questions
Is this image compressor really free?+
Yes. Compression happens entirely in your browser — no server is involved, no image is uploaded, and there is no limit on how many files you compress.
How much can I compress an image?+
Photos at 70–80% quality typically shrink 3–5× with no visible difference, and often 10× or more at aggressive settings. The live size readout tells you exactly where you stand before you download.
What is the difference between JPG, PNG and WebP export?+
JPG is the smallest for photos but has no transparency. PNG keeps transparency and is sharp for graphics, but files are bigger. WebP is the modern sweet spot: photo-level compression with optional transparency. Use JPG for photos, PNG for logos, WebP for the web.
Is my original file modified?+
Never. The compressed copy is generated as a brand-new download; the original stays exactly as it was on your device. Nothing is ever uploaded or saved anywhere.
