Frequently asked questions

Is this PDF compressor free?

Yes. It is free to use. No sign-up or install is required, and everything runs directly in your browser.

Will image quality drop after compression?

It depends on the original PDF and your settings. Target Size mode prioritizes your size goal, while Advanced mode lets you fine-tune DPI and JPEG quality.

Are PDF files uploaded to external servers?

No. Loading, compression, and saving are all processed locally in your browser.

Can I still search and copy text after compression?

Yes in most cases. The tool keeps the text layer when present and mainly recompresses embedded images.

What happens if the target size cannot be reached?

The tool retries with adjusted DPI and quality. If it cannot hit the exact goal, it chooses the closest result under your limit or the smallest practical output.

Are password-protected PDFs supported?

Only PDFs that can be opened without a password are supported. Encrypted files will return an error.

What is PDF compression? A safe, free way to shrink PDF files

What PDF compression means

PDF compression reduces file size while keeping your document readable. It is useful for email attachments, web publishing, cloud storage, and team sharing where file limits and loading speed matter. This tool lets you compress PDFs for free in your browser using target size controls and practical presets.

When you need to meet email attachment limits

Set limits like 5 MB or 10 MB and tune output size to reduce send failures while keeping files easier to share.

When you want lighter files for web and cloud use

Use web-focused or archive-friendly presets to lower file size while keeping documents clear and reducing storage and load overhead.

When privacy matters and uploads are not acceptable

All processing is done locally in your browser, and your PDF is never uploaded to external servers. No installation is needed, and it works on desktop and mobile. It is suitable for business documents, invoices, forms, and other files that need safer handling.
