The 1 MB target uses local candidate renders; neither the source PDF nor rejected candidates are uploaded.
Check these before you start
- One megabyte is a target rather than a guaranteed ceiling.
- Dense color scans may need stronger reduction than text documents.
- The result is image-based and may need OCR afterward.
Fit an application attachment
- Input
- A six-page 7.2 MB application packet
- Result
- The best locally generated candidate toward 1 MB, ready for a portal size check.
1 MB target
One megabyte is a practical starting point for short application packets that need more readable detail than ultra-small presets permit.
Open the preset tool →Good fit for this job
- ✓ An application portal asks for about 1 MB
- ✓ The PDF is a short text document or moderate scan
- ✓ You need a balance between legibility and upload size
When to use another option
Use 2 MB for photo-heavy certificates or longer packets.
Use the email preset when there is no 1 MB requirement.

Practical answers
Does Compress PDF to 1MB guarantee exactly 1 MB?
No. It selects the smallest practical candidate toward the target and displays the real result. Some PDFs cannot reach 1 MB without becoming unreadable.
What should I do if the result is still above 1 MB?
Remove unnecessary pages, crop large margins, or split the document. Do not repeatedly compress an already degraded copy.
Verify the privacy claim yourself
The 1 MB target uses local candidate renders; neither the source PDF nor rejected candidates are uploaded. You can inspect your browser Network panel while the job runs to confirm whether any PDF body leaves the device.
