Compress images for WhatsApp
WhatsApp already crushes the photos you send — so compress them yourself first and stay in control of the quality. Set a target size like 100 KB, watch the before/after preview, and download a photo that sends instantly and still looks good, all without uploading anything.
Privacy-first: every image is processed locally in your browser. Nothing is uploaded, stored or transmitted to any server.
Beat WhatsApp’s own compression
When you send a photo the normal way, WhatsApp re-encodes it on its servers with settings you never see, which is why forwarded images slowly turn mushy. Compressing to a sensible target yourself — around 100 KB is plenty for a phone screen — means the app has far less to strip away, so what your recipient opens is much closer to what you approved. The before/after slider here shows you the trade-off before you commit.
Small enough to send on any connection
A 100 KB image sends in a blink even on a weak signal, and it barely touches a data cap when you are sharing dozens of them. Point the compressor at a target size and it does the math for you, nudging quality until the file fits. Everything runs on your device, so the photos — often personal ones headed to family and friends — are never uploaded to a compression service on the way.
Frequently asked questions
- Does my image get uploaded?
- No. All compression happens locally in your browser using the Canvas API. Your files never leave your device and are never sent to a server.
- Does compression reduce quality?
- Lossy formats (JPG, WebP, AVIF) trade a little quality for much smaller files, and the quality slider lets you find the right balance. PNG is lossless, so it stays pixel-perfect.
- Which formats are supported?
- You can compress JPG, PNG and WebP. You can also convert a PNG photo to WebP during compression for much smaller files.
- Can I compress to a specific file size?
- Yes. Switch to “Target size” mode and PixelVault searches for the highest quality that fits under your chosen KB limit.
- Can I compress multiple images at once?
- Yes. Drop in as many images as you like and download them individually or together as a single ZIP file.
