How to compress images in your browser
Drop in images
Drag and drop, click to browse, or paste an image from your clipboard. Multi-select is supported.
Pick a preset or tweak options
Hit a preset like Web optimized, or set output format, quality (0.8 is the sweet spot), and max width. You can also set a target file size — the tool iterates quality until it fits.
Compress & compare
Each card shows original size, compressed size, and savings. Click a thumbnail to open the side-by-side comparison slider.
Download
Click a single card's download icon, or "Download all" to save the whole batch (browsers may prompt for each file).
Frequently asked questions
No. Compression runs entirely in your browser via Canvas and a Web Worker. The image bytes never leave your device.
JPEG, PNG, and WebP for both input and output. HEIC inputs are decoded into a Canvas (Safari does this natively) and re-encoded to your chosen format. AVIF output depends on your browser.
Yes. The Canvas re-encode drops EXIF, GPS, IPTC, and XMP. To confirm what was removed, run the original through our EXIF Viewer first.
You set a target quality between 0 and 1. 0.8 is the typical sweet spot for photographs. PNG output is lossless and ignores the quality value.
It can happen when re-encoding a heavily-compressed JPEG, or when converting a small PNG with few colors to JPEG. The card highlights this in yellow — keep the original in that case.
About browser-side image compression
This tool wraps a Canvas re-encode loop in a Web Worker so the main thread stays responsive while compressing large or many images. Internally it uses browser-image-compression, which gives you per-file controls and a max-size iterator.
What gets stripped
- EXIF (camera, settings, sometimes GPS)
- IPTC and XMP editorial blocks
- Embedded thumbnails (often hundreds of KB on their own)
- ICC profiles (most browsers fall back to sRGB safely)
Tips for the best ratio
- Photos: WebP at quality 0.75–0.85 is usually 30–50% smaller than equivalent JPEG.
- Screenshots / UI: keep PNG; consider WebP-lossless if your browser supports it.
- Hero images: cap max width at 1920–2560px — beyond that is rarely visible.
