How to prepare documents for online applications

Portals reject the wrong format, oversized files, and sometimes unexpected metadata.
On A2Z Edit, convert photos to PDF, compress under the limit, and redact anything the form should not see.
How to prepare documents for online applications
- Read the portal’s format and size rules first.
- Convert images to PDF when required.
- Merge related pages into the asked packet.
- Compress until under the cap.
- Redact unrelated personal data that the form does not request.
Why it matters
Preparation up front beats discovering an upload error at midnight.
Tips
- Name files exactly as the instructions specify.
- Keep originals; upload derivatives.
- HEIC from phones usually needs JPG or PDF conversion first.
Frequently asked questions
Image or PDF?
Follow the listing—when unsure, PDF packets are common for multi-page proofs.
Color vs scan?
Readable contrast matters more than fancy color.
Multiple certificates?
Merge or upload separately per the form’s fields.
