A modern phone photo weighs 3 to 8 MB. Getting it under 1MB takes one or two adjustments and leaves a picture that still looks full quality. Drop your photos below and watch the size update live.
Phone cameras save at very high quality settings to be safe, and most of that data is invisible. Re-saving at 85% typically halves the file with no change you can find even when zooming in. The rest of the saving comes from trimming pixels no screen will show.
Compared with tighter limits, you keep enough resolution to crop later. A 2560 px photo can lose a third of its frame and still fill a laptop screen.
Email is the main case. Most providers cap a message around 20–25 MB, and attachments grow by about a third in transit. At 1MB each, fifteen photos fit safely in one message.
It is also a good size for shared albums, cloud storage you pay for by the gigabyte, and upload forms with a 1 or 2 MB cap. For pictures embedded in a web page it is too heavy: go to 200KB or below there.
Limit the long side to 2560 px and set quality to 85%. That alone brings most 5MB phone photos to between 600KB and 1MB.
Yes, up to about A4. A 2560 px image prints at roughly 20 cm wide at 300 DPI, and looks fine larger when viewed from normal distance.
It is probably very detailed or still very large in pixels. Lower the maximum dimension to 2048 px, or the quality to 78–80%, and it will pass.
By default, yes. Location, camera model and date stored in the file are dropped when the image is re-encoded, which also saves a few kilobytes.
