How to Compress a PDF to Under 1MB
To compress a PDF to under 1MB, open the Compress PDF tool, enter 1 MB as your target size, and choose the Strong preset. The tool downsamples and re-encodes embedded images automatically and reports the exact size it achieved. If your PDF is mostly text with few images, compression may have little effect — that's expected, since there's less to compress.

Why 1MB is a common target
Many email providers and government/HR upload forms cap attachments around 1-2MB. Scanned documents and PDFs with high-resolution photos are the most common files that exceed this — text-only PDFs rarely do.
Step-by-step
1. Open the Compress PDF tool and upload your file.
2. Enable "Try to get under a target size" and enter 1048576 bytes (1 MB), or use the placeholder shortcut.
3. Select the Strong preset for maximum size reduction.
4. Review the before/after size shown after processing, and a preview of representative pages.
5. Download the compressed file.
If it can't reach 1MB
A target size is always best-effort — the tool will never silently discard content or degrade quality below a sane floor just to hit an arbitrary number. If a PDF genuinely can't shrink to your target (e.g. it's already highly compressed, or is mostly vector graphics/fonts), the honest answer is that a smaller output isn't available without visibly damaging the document.

Will compressing to 1MB make my PDF blurry?
Possibly for photo-heavy pages under the Strong preset — that's the size/quality tradeoff. Use the Balanced or High quality preset instead if visual fidelity matters more than hitting an exact size.
