Read the limit, not just the error
Some forms say “max 100 KB”, others only “file too large”. If the page documents a number, write it down — that is your target. Common caps are 100 KB, 200 KB, 500 KB, and 2 MB.
If no number is shown, start with under 200 KB; government and job portals often sit near 100–200 KB.
Compress first, then resize if needed
Compression lowers quality slightly without changing pixel count. Resizing cuts width/height and usually saves more bytes when the photo is thousands of pixels wide.
Use Compress to 100 KB or Compress to 200 KB when you have a hard cap. For softer goals, Image compressor lets you pick quality by eye.
If the result is still over, resize to the size the form actually displays (often under 1200 px wide), then compress again.
Format matters
PNG screenshots and logos stay large. Forms that want photos usually expect JPG. Convert with PNG to JPG or pick JPEG on the compressor.
iPhone HEIC files confuse many Windows portals — convert with HEIC to JPG first.
Privacy note
ID photos and application scans are sensitive. Prefer tools that process in the browser so the file is not uploaded to a random converter server. DeepConvert’s compress and resize pages run locally on your device.

Open the target compressor, drop your photo, and download when the size readout is under the cap.
