Why compress images before sending on WhatsApp?
WhatsApp compresses everything
WhatsApp reduces every image you send to roughly 80–200KB automatically. If you pre-compress to 200–300KB first, WhatsApp has less work to do and the recipient sees a much sharper image.
Save mobile data
A 5MB camera photo uses 5MB of your mobile data to send. Compress to 300KB first and use 94% less data — critical if you are on a limited plan or sharing in a large group.
Faster sends and downloads
Smaller images send instantly even on slow connections. Recipients in 2G or poor network areas can view your photos immediately rather than waiting for a large file to download.

Frequently asked questions
At the quality levels used in this tool (82–88%), the human eye cannot reliably detect compression at normal viewing distance on a phone screen. The tool also scales images to the optimal resolution for each use case first — this achieves most of the size reduction without any quality loss at all, since the extra pixels were never going to be displayed at full size anyway.
WhatsApp resizes any image to a maximum of 1600px on the longest side and applies its own compression before sending. Pre-compress to 1600px at quality 82% — your image will then pass through WhatsApp's compression with minimal additional quality loss, producing a significantly sharper final image than sending the original 5MB camera file directly.
No. All compression happens entirely in your browser using the Canvas API — the same technology browsers use to render web graphics. Your photos never leave your device. No upload, no server, no data collection. You can verify this by watching your browser's Network tab — no image data is sent anywhere during processing.
Yes. Upload as many images as you need in one go, or add more to the queue at any time by dropping more files onto the add-more zone. Each image compresses and shows its individual result. When done, download them all as a single ZIP file with one click.
WhatsApp applies its own compression to every image sent in chat, reducing a 5MB photo to roughly 80–200KB. When a 5MB image gets squeezed to 80KB, significant detail is lost — especially in fine textures and areas with small text. If you pre-compress to 200–300KB before sending, WhatsApp barely needs to touch it further, preserving much more detail.
Yes. The tool compresses PNG files. For photographic PNG images, compressing to JPEG achieves a significantly larger size reduction since JPEG is designed for photos. For screenshots and graphics with sharp text or logos, the tool keeps quality high to avoid blocky JPEG artefacts around text edges.
82–85% quality at 1600px maximum dimension is the proven optimal WhatsApp setting. This produces files in the 150–350KB range — small enough that WhatsApp's own compression barely needs to reduce them further, preserving more detail in the final image the recipient sees.
