Frequently asked questions
What does the Quick PDF Preview tool do?
Quick PDF Preview lets you quickly preview a pdf in a modern browser reader. It runs entirely inside your browser so your files stay on your device — nothing is uploaded to a server.
Is Quick PDF Preview really free to use?
Yes. Quick PDF Preview is 100% free, with no signup, no watermark and no daily limit. You can process as many PDFs as you want.
Do I need to install any software?
No. Quick PDF Preview is a web-based tool that works in any modern browser — Chrome, Edge, Safari, Firefox and Brave — on Windows, macOS, Linux, Android and iOS.
Are my files safe with Quick PDF Preview?
Yes. Quick PDF Preview processes every file on the client side using JavaScript. Your PDF is never uploaded, stored or shared. Close the tab and it's gone.
Does Quick PDF Preview work on mobile devices?
Yes. Quick PDF Preview is fully responsive and works on Android phones, iPhones and iPads. Just open the page in your browser and pick a file.
Is there a file-size limit for Quick PDF Preview?
We recommend files under 100 MB for the smoothest experience. Larger files may work but can slow down older devices because everything is processed in your browser.
Will Quick PDF Preview reduce the quality of my PDF?
Quick PDF Preview keeps the original quality wherever possible. Any quality trade-offs (for example when compressing or exporting to images) are clearly labelled and controlled by you.
Can I use Quick PDF Preview without an internet connection?
You need internet to load the page the first time. After that, most processing happens locally in your browser — the PDF itself never travels over the network.
Does Quick PDF Preview add a watermark?
No. Files produced by Quick PDF Preview are clean, watermark-free and safe to share professionally or submit to official portals.
Can I use Quick PDF Preview for commercial or client work?
Yes. There are no licensing restrictions on the output — use it for freelance projects, agency work, client deliverables or internal business documents.
Which PDF versions does Quick PDF Preview support?
Quick PDF Preview supports standard PDF 1.4–1.7 files created by Word, Google Docs, Adobe Acrobat, printers, scanners and mobile apps. Encrypted PDFs must be unlocked first.
Why is my PDF password-protected file rejected?
For security we don't process encrypted PDFs. Use our PDF Password Remover first (if you have the password), then run the file through Quick PDF Preview.
Can I quick pdf preview more than one file at once?
Yes — where it makes sense (for example merging or converting), Quick PDF Preview accepts multiple files at once and processes them in a single click.
What browsers work best with Quick PDF Preview?
Any Chromium-based browser (Chrome, Edge, Brave, Opera) or the latest Safari and Firefox will give the best speed. Older browsers may lack the modern APIs the tool relies on.
Does Quick PDF Preview keep my PDF's bookmarks and links?
Structural features like bookmarks, hyperlinks and metadata are preserved wherever the operation allows. Conversions to image formats (JPG, PNG, PPT) naturally flatten these into pixels.
How long does Quick PDF Preview take?
Most PDFs under 20 MB finish in a few seconds on a modern laptop or phone. Larger files take proportionally longer because everything is computed on your device.
Can I undo an operation performed by Quick PDF Preview?
Quick PDF Preview never modifies your original file — it creates a new PDF and downloads it. Your source file on disk stays exactly as it was.
Do you store logs of my uploads?
We can't — nothing is uploaded. There are no server logs of your file names or contents because your PDF never leaves the browser tab.
Is Quick PDF Preview better than desktop apps like Adobe Acrobat?
For quick one-off jobs, Quick PDF Preview is faster: no install, no license, no waiting. Acrobat is still the choice for heavy editing workflows — Quick PDF Preview covers 90% of everyday needs.
