How to Reduce a PDF Under 1MB
Practical steps for trying to meet a 1MB upload target without promising a fixed compression ratio.
# How to Reduce a PDF Under 1MB
A 1MB target may be required by an application or upload form. Whether a PDF can reach that size depends heavily on its contents.
## Steps
1. Check the destination's exact file-size limit.
2. Open PDFilio's Compress PDF tool.
3. Upload the PDF within the tool's current limit.
4. Select an available compression level.
5. Check the resulting size and review readability.
## If it remains above 1MB
Remove unnecessary pages, reduce oversized images in the source, or split the document if the destination allows multiple files. Do not sacrifice legibility just to reach an arbitrary size target.
