Frequently asked questions
How do I compress a PDF to exactly 1MB?
Open Compress to Size, choose “Under 1 MB” and click the button. The tool measures your file, calculates the ideal quality, and produces a PDF under 1MB automatically — no manual slider tweaking.
What if my PDF can't reach the target size?
The tool will tell you honestly and deliver the smallest readable result. This happens with text-heavy files that are already efficient, or when the target is extremely small for the page count.
Will my text stay readable?
Yes. The tool reduces image quality first and protects text sharpness. Pages remain fully readable at normal zoom.
Is there a file size limit?
Only your device's memory. Most phones handle files up to a few hundred MB.
Do I need to upload my file?
No — everything runs in your browser. Your PDF never leaves your device.
What's the difference from regular Compress PDF?
Compress PDF gives you a manual quality slider; Compress to Size takes a target (like “under 2MB”) and finds the right quality for you automatically.
Shrink oversized PDFs so they fit email attachments and upload limits. PDFZippy compresses your PDF locally in your browser — pick a target size like 1MB and download a smaller file in seconds. Most PDFs shrink dramatically on the first pass — try it and check the before/after sizes.
How to compress a PDF
Open your PDF in the Compress PDF tool.
Drag the quality slider: left for a smaller file, right for sharper pages.

Tips for best results
Need to hit a size limit (like 1MB for email)? Start near 50% quality and nudge the slider until the result fits.
Compress a copy first if you need the original quality archived somewhere.
Image-heavy PDFs shrink the most — text-only files are already small.
If email still rejects the file, try one step stronger compression.
Frequently asked questions
How do I compress a PDF to 1MB?
Open the file in Compress PDF and drag the quality slider — left for the smallest file, right for sharper pages. To hit an email size limit, start around 50–60% and adjust until the result fits; the tool shows the exact before/after sizes.
How much smaller can my PDF get?
It depends on the file — image-heavy PDFs often shrink 70–90%, while text-only PDFs are already small and may barely change. The tool shows you the exact before/after sizes.
Will compressing make my PDF blurry?
Text stays sharp because compression targets images, not text. At aggressive settings images may lose some detail — preview the result and pick the balance you like.
Why is my PDF so large in the first place?
Usually uncompressed images or scanned pages. Each scanned page can be several MB; compression re-encodes those images efficiently.
Is there a maximum file size I can compress?
The limit is your device's memory rather than a fixed number. Most phones handle files up to a few hundred MB; desktops handle more.
Do I need to upload my PDF to compress it?
No. Compression runs entirely in your browser — your file never leaves your device.
