About this tool
WRRK's image compressor reduces JPG, PNG, and WebP file sizes by up to 80% without visible quality loss. The whole process runs in your browser — your photos never get uploaded to a server, which makes it both faster (no upload wait) and private (no copies left on anyone else's machine).
Drop a single image or a batch of 50+ at once. For each image, you'll see the original size, compressed size, and percentage saved. Adjust quality from 10% to 100% to balance file size against fidelity — the default 80% setting is a sweet spot most photographers and web designers use.
How to use
- Drag images onto the drop zone, or click to pick files.
- Set the quality slider — 80% is the default sweet spot.
- (Optional) Pick output format — keep original, or convert to WebP for the smallest size.
- Click Compress and wait a few seconds.
- See the before/after file size for each image.
- Download individually, or grab all at once.

Frequently asked questions
+−How much can I compress a JPG without losing quality?
Most JPGs can be compressed by 60-80% with no visible quality loss at 80% quality setting. Photos with lots of fine detail (foliage, fabric texture) handle compression better than flat graphics or screenshots.
+−Does compressing a PNG lose transparency?
No. PNG compression is lossless — transparency, sharp edges, and exact pixel values are preserved. You're just removing redundant data, not visual information.
+−What's the difference between compressing JPG vs PNG?
JPG uses lossy compression — great for photos, terrible for text and logos. PNG uses lossless compression — perfect for graphics with transparency, screenshots, and logos, but produces bigger files for photos.
+−Are my photos uploaded to your server?
No. Compression happens entirely in your browser using JavaScript. Your images never leave your device, which is why this tool works offline once loaded.
+−Can I compress multiple images at once?
Yes. Drop as many as you want — there's no batch limit. Each image is compressed in parallel.
+−Should I use WebP instead of JPG?
WebP files are typically 25-35% smaller than JPGs at the same visual quality. Every modern browser supports WebP. Use it for websites; stick with JPG for files you'll email or upload to legacy systems.
