Create smaller image files for websites, email and sharing.
Smaller images can speed up pages, fit into attachment limits, and use less storage. QuickTools lets you experiment with compression settings without installing a program.
Image quality and output size are connected: lower quality settings may reduce file size but introduce visible artifacts. Some source formats also behave differently when re-encoded. Always preview an important photo before replacing the original.
Frequently asked questions
Which formats can I compress?+
JPG, PNG, and WebP are supported in modern browsers.
Can image compression reduce visual quality?+

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.
