What is the short answer?
Read the portal's format, pixel and file-size rules first. Add the original photo, select the nearest target below the maximum, then inspect the face, signature or document text before downloading.
What requirements should you copy from the form?
Write down the accepted format, maximum file size and any required width, height or aspect ratio. A 200 KB limit is different from a 200 KB target: leave a little room below the maximum because portals may calculate size differently.
How should you compress the photo?
Use JPG for an ordinary camera photo unless the application explicitly requests PNG. Start with the target-size control. The compressor reduces encoding quality first and may reduce dimensions proportionally when quality changes alone cannot reach the limit.
What details must remain readable?
Zoom into eyes, facial edges, printed numbers and signatures. Reject a result with blocky edges, smeared text or a face that has become too small. Return to the original and use a less aggressive target when the form allows it.
How should you handle sensitive images?
Remove unrelated personal information before processing or submission. CollagePlus processes selected files in the browser, but the destination portal has its own privacy policy. Confirm the address and organization before uploading identity documents.
What should you check before submitting?
Open the downloaded copy, confirm its extension and file size, and make sure the orientation is correct. Upload that copy while keeping the original unchanged in a separate location.
