MADE TO BE EASY

Make image-heavy or scanned PDF documents easier to share.

Large PDF files are inconvenient for email attachments, sharing, and online submission forms. Documents that contain many scanned pages or high-resolution pictures may benefit from image-based compression.

Compression is not guaranteed to make every PDF smaller. Already optimized files may remain the same size or even grow. Strong image compression can rasterize pages, making previously selectable text unavailable. Keep your original if editable text and sharp details matter.

GOOD QUESTIONS

A little more clarity.

Is QuickTools really free?+

Yes. Every tool on this page is free. No account, subscription or credits are required.

Are my files uploaded to a server?+

No. PDF and image tools process files in your browser, not on our server. To process PDFs, third-party libraries load from trusted CDNs. If you choose to send a tool suggestion, only your written suggestion is sent to our database.

Which image formats are supported?+

JPG, PNG and WebP are supported in modern browsers. Animated images are not preserved as animations.

Why can a compressed file sometimes be bigger?+

Already optimized files can grow when re-encoded. PDF image-compression may remove selectable text. Choose the quality setting appropriate for your document.

Does PDF to Word preserve complex layout?+

No. This browser-only converter extracts selectable text into an editable DOCX. Graphics, complex tables, fonts and scanned pages are not converted accurately.

Is PDF compression lossless?+

Use text-preserving rewrite for modest optimizations. Stronger scan compression rasterizes pages, so text selection, vector detail, links and forms are lost.

How do tool suggestions work?+

Suggestions are saved only when our Cloudflare submission service has been enabled. We collect the category and description you submit, without asking for your email. To limit spam we may temporarily process a non-reversible visitor identifier. Please do not include personal information in your message.
