WhatsApp Image Compressor — Free
WhatsApp re-compresses every photo it forwards. Pre-compressing the image before you send means WhatsApp's compressor has less room to degrade what you sent.
Why pre-compress for WhatsApp?
If your source is a 5 MB phone photo, WhatsApp's algorithm hits it aggressively. If you pre-compress to ~600 KB at quality 70, WhatsApp's second pass barely changes it — the recipient sees a sharper image.
Send as document for full quality
WhatsApp's Send as Document option bypasses re-compression entirely. Compress to a sensible size first, then attach via document to preserve every detail.
Frequently asked questions
Does WhatsApp resize images?
Yes. It also caps the long edge around 1600 px. Resize before sending if you need a specific dimension.
Is it actually free?
Yes. No signup, no daily cap on normal personal use, no watermark on the output. Display ads keep the site free.
Does it work on a phone?
Yes. The upload box opens the camera roll on mobile browsers directly.
