Choose photos
Select the pages you need without granting broad photo-library access.
Photos to PDF for strict upload limits
Make the PDF your portal will accept.
Choose photos, arrange the pages, set a limit such as 500 KB or 1 MB, and get one measured PDF. SizeProof never calls an oversized file “ready.”

How it works
From camera roll to verified PDF in four steps.
Put them in order
Reorder, rotate, or remove pages before creating the document.
Set the real limit
Choose a preset or enter the KB or MB limit shown by the application portal.
Share the measured file
Preview the completed PDF and save or share it only after its final size is checked.
Built for trust
Readable when possible. Honest when it is not.
If the pages cannot fit under the chosen limit without dropping below SizeProof’s readability floor, the app explains the problem and offers accurate next steps.
- Exact final byte measurement
- A4, US Letter, automatic, and ID-friendly pages
- On-device document processing
- No account or cloud document upload
Common questions
Before you start
Can SizeProof guarantee every target size?
No. Some page sets cannot remain readable under an extremely small limit. SizeProof reports that honestly instead of claiming a false success.
Are my documents uploaded?
No. Photo-to-PDF processing happens on your device. Read the privacy policy for optional analytics and rewarded-ad details.
