SmartShrink PDF

Upload the PDF and SmartShrink measures how much of each page is used. "Keep full size" combines mostly-empty pages without shrinking their text, and 2 or 4 pages per sheet places whole pages side by side. You see the new page count before anything is made.

Not on the default setting. 'Lossless' only combines pages whose content fits together at its original size. It finds where the content is on each page, crops to that, and stacks the pieces. The text keeps its size and stays selectable. The Balanced and Maximum settings do shrink content, and each one tells you the exact percentage before you commit.

Because most pages are mostly empty. A page with a heading and three lines uses about 4% of the sheet, so four of those fit on one page with room to spare. Nothing is removed. The same content uses less paper.

Yes. Choose 2 or 4 pages per sheet and every page is placed whole, scaled down to fit its space, in the original order, with nothing cropped. That halves or quarters the page count, which is handy for printing handouts or reading on a large screen.

Because its pages are already full. Slides, scans and image-heavy documents fill the sheet edge to edge, so combining any two would mean shrinking them. The tool tells you this instead of making a poor result.

With "Keep full size", pages that have them are never combined and are copied across untouched. The 2 and 4 pages per sheet layouts place every page, so links, comments and form fields are lost there. Keep the original if you need them.

Compress PDF makes the file smaller in megabytes and leaves every page as it is. SmartShrink reduces the number of pages, which is what matters when you print or read on screen, and then runs a compression pass as well, so the file usually gets smaller too.

Yes. The suggestions all start switched on, and you can switch off any group. The page grid shows which pages would go together, and the total updates as you change your mind.

Usually. Combining pages makes the file bigger at first, so it is compressed at the end, and the result is normally smaller than the original. Both sizes are shown on the result screen, whichever way they went.

SmartShrink works in several steps, so it keeps your file while you use it. The file is deleted as soon as your new PDF is made. If you close the tab part-way through, it is deleted automatically within 30 minutes.

Yes. Every tool works without paying and without an account. Files can be up to 200 pages and 80 MB, and a run that fails costs you nothing.

No. All tools work without signing in. An account raises your hourly allowance and lets you see what you have processed.
