Compress photos for forms

School, visa, and job portals often want a JPEG under a tight cap: 50 KB, 200 KB, 1 MB. Phone cameras shoot well above that. Compress Image reduces the file in the browser so you can see the result before you upload. The goal is “the officer can still recognize the face,” not the smallest number on the disk.

Crop before you squeeze

Background walls, a table, and empty sky waste kilobytes. Crop to the required aspect if the instructions give one (passport photos often want a square or a 35×45 mm crop). Then compress. Resize Image does both in one pass: it crops to an exact size such as 35 x 45 mm or 600 x 600 pixels and can keep the file inside a KB range. Compressing a huge uncropped photo and hoping the portal crops it for you usually fails both the size cap and the composition rules.

Faces, text, and receipts

Faces need enough pixels that both eyes are distinct at the size the form displays. If the compressed preview turns skin into blotches, raise quality or crop tighter instead of shrinking the whole frame. Text on a receipt or an ID card needs contrast. A JPEG that smears serial numbers is smaller and useless. For mixed pages already in a PDF, use Compress PDF rather than extracting every page as a photo unless the portal wants images.

Formats the form actually accepts

If the field says JPEG, export JPEG. An iPhone photo saved as HEIC needs converting first, so run it through HEIC to JPG before you compress it, or use the steps in how to convert HEIC to JPG. PNG is larger and some older portals reject it. WebP is smaller but still blocked on many government sites. Do not rename a PNG to .jpg. The portal checks the file, not just the extension.

Keep the original. If the first upload is rejected for being too small (some visa sites reject blurry photos), you can recrop from the original instead of from the compressed copy. Processing stays on your device until you submit; see what stays on your device.
