Resize JPG

We recommend resizing photo width to 1920px (Full HD) with JPEG quality set to 85%, which keeps file sizes well under 1MB while preserving sharp details.

Resize first, then compress — and once you have resized, you can push the quality slider lower than you normally would. Downscaling throws away the fine detail that JPEG compression artifacts hide in, so a 1920px photo tolerates quality 80 about as invisibly as a 6000px original tolerates 90. Doing it the other way round wastes the compression work, because the resize afterwards discards pixels you just spent bytes describing.

Yes, and that is worth knowing before you post a photo publicly. The output is re-encoded from a canvas, and a canvas carries no metadata, so the EXIF block does not survive — camera model, lens, capture timestamp and any GPS coordinates the phone recorded are all gone from the resized file. If you specifically need that metadata preserved, keep the original alongside the resized copy.

Match the largest size the image will ever be displayed at, not the largest size you have. A full-width hero on a high-density screen wants around 2560px; ordinary in-article photos 1200-1600px; a messaging app or an email attachment 1920px is already generous, and 1080px is usually indistinguishable. Anything beyond the display size costs bandwidth and page-load time and buys nothing a viewer can see.

Downscaling can make a soft photo look better, because shrinking it compresses the blur into fewer pixels and the eye reads that as sharper. It is not recovering focus — the detail was never captured — so the effect disappears the moment the image is displayed larger again. Genuine motion blur or missed focus cannot be fixed by changing dimensions.
