Frequently asked questions
How do I convert a PDF to black and white?
Open it in Grayscale PDF and click “Make Grayscale”. Every page is converted to black & white while keeping the exact layout.
Will it affect the layout?
No — only colors change. Text positions, images and page sizes stay identical.
Why convert to grayscale before printing?
Color ink/toner costs far more than black. Grayscale printing is cheaper and often faster.
Can I convert back to color?
No — the conversion is one-way. Keep your original file if you need color later.
Does it work on scanned PDFs?
Yes — scanned pages convert just like any other PDF.

How to compress a PDF

Why use PDFZippy for this

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.
