Our engine selectively downsamples high-resolution images, removes redundant embedded fonts, and cleans up unnecessary metadata and hidden layers without touching the text.
Frequently Asked Questions About Compress Pdf
Compression Techniques
Will the compressed PDF look blurry?
We use smart compression algorithms that maintain excellent visual quality for screens and standard printing. Text and vector graphics remain razor-sharp.
Can I choose the level of compression?
Yes, you can typically select between 'Recommended' (best balance of size and quality) and 'Extreme' (smallest possible size, with minor visual degradation in images).
Use Cases & Limits
Is this tool suitable for compressing documents for email?
Perfectly. It is specifically designed to shrink large reports, portfolios, and scanned documents so they easily fit under the standard 25MB email attachment limit.
Why didn't my PDF shrink very much?
If your PDF consists entirely of text or vector graphics with no images, it is already highly optimized. Compression tools yield the most dramatic results on image-heavy PDFs.
Does compressing a PDF remove its passwords?
No, if you upload a password-protected PDF, you must unlock it first. The resulting compressed file will not retain the original encryption; you would need to re-protect it.
