Frequently Asked Questions
Does WhatsApp compress photos?
Yes. In standard quality WhatsApp resizes photos to about 1600px on the longest side and recompresses them at roughly 70% JPG quality, so a 4 MB photo usually arrives at 200-400 KB. Sending it as a Document keeps the original.
Does Telegram compress photos?
Yes, but less than WhatsApp. Telegram resizes photos to 2560px on the longest side at about 85% JPG quality. Sending as a File keeps the original.
Which app keeps the best photo quality?
Of the apps tested here, Telegram keeps the most detail when sending as a normal photo. Discord and Slack do not recompress uploads at all, and every app keeps the original when you send it as a file or document.
Is my photo uploaded anywhere?
No. The test runs in your browser using a canvas: the photo is resized and re-encoded on your device and never sent to a server.
