Online PDF converters are convenient right up to the moment your document contains a contract, an ID or internal reporting: the file lands on someone else's server and what happens next is out of your hands. HyperPDF does the same jobs inside a browser tab, so the document never leaves your machine.
The second job is comments. Reviewer feedback often gets lost in forwarding or simply does not render in free viewers. HyperPDF shows highlighted passages, authors, dates and reply threads, and can write it all back into the PDF as standard annotations or print it in the margins with numbered flags.
What it does HyperPDF
Merge files
Drag several PDFs into the window and they combine into one document in the order you choose.
Delete and reorder pages
Remove unwanted pages in a click and rearrange the rest with the mouse.
Rotate by 90°
Straighten sideways scans page by page.
Export selected pages
Tick the pages you need and save them as a separate file — handy when only the appendix should go out.
Compress at 150 / 110 / 72 DPI
Three presets, from barely noticeable loss to the lightest possible file for email.
PDF from images
Turn JPG and PNG files into a single PDF — for scans, photographed documents and signed forms.
Read reviewer comments
Notes, highlights and underlines with author, date and the quoted passage; reply threads are shown in full.
Add your own comments
Reply inside existing threads or leave new notes, then save them as ordinary PDF annotations or print them in the margins with numbered flags.
How to use it
- Click the HyperPDF icon and drag one or more PDFs into the window.
- Build the page order you need: delete, rotate, drag to rearrange.
- Pick a compression preset if the file has to get smaller — 150, 110 or 72 DPI.
- Save the result to your computer. The original file is left untouched.
Who it is for
- Combine a contract, its appendices and an invoice into one file
- Drop blank and unwanted pages from a scan
- Shrink a report until it fits your mail server's limit
- Turn photos of signed paperwork into a tidy PDF
- Work through reviewer feedback without buying a paid editor
How to install
Find the extension you need and press Install
The right Chrome Web Store page opens in your browser.
Press Install on the Chrome Web Store page
A blue Install button appears on the right of the listing — click it. If the page opened in a different browser (Safari, say), copy its address into Chrome, Yandex Browser, Edge or Opera and press the button there.
Pin the icon to the toolbar
Open the extensions list in your browser settings and pin the new extension to the toolbar.
Done — open the extension
Click its icon in the browser. No account, no payment, no setup needed.
All four browsers (Chrome, Yandex Browser, Microsoft Edge, Opera) are built on the Chromium platform, so extensions for them all come from one place — the Chrome Web Store. Chrome and Yandex Browser open the listing directly. Edge asks once for permission to install from other stores — choose “Allow”. Opera needs the free Install Chrome Extensions add-on, after which the install button appears on the normal listing page.
Frequently asked questions
Where are my documents uploaded?
Nowhere. Processing happens in the tab's memory; there are no servers, no analytics and no accounts. Close the tab and the files are gone from memory.
How do I compress a PDF to fit an email limit?
Open it in HyperPDF and choose the 110 DPI preset for a balanced result, or 72 DPI for the smallest file. Note that compression rasterises pages, so comments are not kept in the compressed version.
Can I merge several PDFs into one?
Yes — drag the files into the window, arrange them in order, and save the combined document.
Does it open password-protected files?
No. Remove the protection in the application that created the file first.
Is PowerPoint supported?
No, HyperPDF works with PDFs and images. For shrinking presentations use HyperCompress.
Is it free?
Completely — no subscription, no file limits, no watermarks.
