• I deleted the instruction pages from a fillable form and now the fields don't work. What's the fix?The new file does not carry interactive form fields. Fill the form first and save a flattened copy, then delete pages, or send the full form if someone else fills it.
• How do I delete pages from a 450-page scanned PDF on my phone when the thumbnails load so slowly?Thumbnails crawling on a big file? Type the page range straight away without waiting, and stay within the tested limit of 500 pages and 100 MB.
• Some sheets went through the scanner twice, so pages repeat in my file. How do I find and remove the duplicates?A sheet went through the scanner twice? The tool does not detect duplicates, but the thumbnails make them easy to spot. Here is how to remove only the second copy.
• I deleted half the pages but the file size hardly dropped. Why?PDF file size follows the weight of the content, not the page count. Why removing text pages hardly shrinks a file, and when deleting pages does cut the size.
• Every invoice I export from Excel comes out with an extra blank page. Should I delete it each time or fix the spreadsheet?If the blank page shows up on every export, fix the spreadsheet once. For invoices already exported or sent to you, delete the last page in seconds.
• Can I type the pages to delete with spaces instead of commas?The pages field accepts spaces, commas, the Arabic comma and Arabic digits as separators. What is accepted, what is refused, and why you always check the summary.
• After deleting pages, does the new PDF still carry the author name and earlier saved versions of the original?The new file is built from scratch with only the remaining pages, so the author, title and earlier saved versions do not come across. What shows on the pages does.
• I have five files with unwanted pages. Should I delete them before merging or after?Deleting after merging is usually faster: one upload and one pass over the pages. When deleting first is better, with a worked example of how page numbers shift.
• I rotated a page 90 degrees and it came out upside down instead of upright. Why?Rotation is added to the angle already stored in the page, not swapped in, so a page stored at 90 goes to 180. Check the thumbnails and fix it before downloading.
• My page is lying on its side. Do I press Right 90 or Left 90 to stand it up?Look at where the top of the text points: if it points left, press Right 90; if it points right, press Left 90. A quick rule with worked examples from the tool.
• Does rotating just one page break the digital signature on a contract?Yes. Rotation is saved into the file, so the file is re-saved and a digital signature no longer validates, however small the change. When a rotated copy is fine.
• After a double-sided scan every back page came out upside down. How do I fix them all at once?Choose Selected pages, type the even pages and press 180° once. That fixes every upside-down back together, and the thumbnails confirm it before you download.
• Does rotating keep my PDF's bookmarks and links, unlike splitting and merging?Rotation edits each page's orientation value inside the same document and saves it, so the file is not rebuilt as with split and merge. What stays, and how to check.
• How do I rotate all 400 pages of a scanned book without waiting for every thumbnail?Choose All pages and press the rotation button straight away, with no selecting and no waiting for thumbnails. Why export is relatively quick, and the tested limits.
• After rotating, my code still reads the old page width and height. Why?The tool stores the angle as the page rotation and leaves the MediaBox alone, so raw dimensions stay while viewers show the page turned. Reading the right size in code.
• I pressed rotate four times, then download, and it says no page has been rotated. Why?Turns add up and wrap at 360, so four presses of Right 90° cancel out. The other cause: Selected pages with no page selected. How to fix both.
• I made a PDF from phone photos and some are sideways. Should I rotate the photos first or rotate the PDF pages afterwards?If you have not made the PDF yet, rotate the photos first so each is laid out upright. If the PDF exists, rotate its pages with no recompression of the images.
• I received a password-protected PDF with sideways pages. Can the rotate tool fix it?Not while it is protected: the tool refuses encrypted files and never bypasses protection. Ask the sender for a fixed copy, or save an unprotected copy if allowed.
• I downloaded the rotated file and then noticed I turned the wrong page. How do I undo it?Your original never changed, so start from it. If only the rotated copy is left, turn the page back by the opposite angle: Left 90 undoes Right 90.
• A customer sent me a PDF on WhatsApp with sideways pages. How do I rotate it on my phone and send it back?Save the document from the chat to your phone's files, rotate the pages in your browser with the buttons, then share the file ending in rotated back in the same chat.
• I photographed a month of receipts in random order; how do I sort them by date before making one PDF?Receipts photographed in random order? Sort them in the tool's list with move up and move down, drop the extras, then build one PDF for your accountant.
• A portal only accepts a PDF up to 2 MB and my five photos are bigger; how do I get under the limit?Portal wants a PDF under 2 MB and your photos are bigger? Split the limit across the photos, compress each to its share first, then convert and read the size.
• My client is in the US; should my scanned documents PDF use A4 or Letter pages?The real difference between A4 and Letter when you turn document photos into a PDF, what changes on the page, and when to choose each one.
• Why did the top and bottom of my product photo get cut off in the PDF?Why edges disappear when you turn an image into a PDF: fill and crop, or original size. How to read the crop warning and get the whole picture back.
