📱 WhatsApp Limits
WhatsApp compresses images above 5 MB automatically, often with visible quality loss. Use our WhatsApp preset to stay under 1 MB for sharp, fast-loading photos.
🔒 100% Private
All compression happens inside your browser using the Canvas API. Your images never leave your device. No server, no storage, no tracking.
⚡ How It Works
We draw your image onto an HTML canvas and re-export it at your chosen quality level. JPEG compression typically reduces file size by 60–85% with no visible difference on a phone screen.
📦 Batch Compress
Select multiple images at once. All files are compressed to your chosen quality setting and individually downloadable — no ZIP required.
Frequently Asked Questions
How much can I compress an image?
At WhatsApp quality (60%), most photos shrink by 70–85%. A 4 MB DSLR photo typically compresses to under 600 KB with no visible quality loss on a phone screen.
Does my image get uploaded to a server?
No. Everything happens in your browser using JavaScript and the Canvas API. Your photos never leave your device. This makes the tool both fast and completely private.
What formats are supported?
JPG/JPEG, PNG, and WebP. Compressed output is always JPEG for maximum size reduction. PNG transparency is preserved when possible.
Why does WhatsApp still compress my image after I compress it?
WhatsApp re-compresses images above ~1 MB. Use our WhatsApp preset (quality 60%) to get under 1 MB — this prevents WhatsApp from applying any further compression.
Can I compress multiple images at once?
Yes. Click the browse button and select multiple files, or drag and drop several images at once. Each file is compressed and available to download individually.
