Questions
- How to convert PDF pages to imagesHow to turn PDF pages into images, what DPI means, what pixel size you will get before converting, and when to choose PNG or JPEG.
- I only need page 7 of a catalog as an image; do I have to convert the whole file?Need only page 7 of a catalog as a picture? Type the page number in the pages field and convert it alone, with no ZIP and no waiting for the rest.
- Why was my A0 floor plan PDF page refused when I tried to convert it at 300 DPI?An A0 page at 300 DPI needs an image over 9900 px on a side, beyond what a browser can draw. Here is the highest setting that fits and how to find it.
- My catalog has 250 pages and the converter handles 100 per run; how do I get images of every page?The converter renders up to 100 pages per run from a file of up to 500 pages. Here is how to split a 250 page catalog into three runs and keep every image in order.
- What is the difference between a zoom factor of 2 and a DPI setting when converting a PDF to images?Zoom and DPI are one scale in two units: zoom equals DPI divided by 72. When each is handier, and why the zoom field accepts values the DPI menu lacks.
- Why does the converter refuse my password-protected bank statement PDF?Password-protected and encrypted PDFs are refused on purpose, and the tool never tries to break the lock. Here is the legitimate route when the file is yours.
- My supplier sent a PDF catalog; how do I get product pictures out of it for my Salla store?Render the catalog pages at high DPI, crop each product and compress it for your store. And why the supplier's original photos still beat anything cut from a page.
- Why is each page image several megabytes when the whole PDF was small?A PDF stores text and shapes as small drawing instructions; an image stores every pixel. Why the image grows, and how DPI, format and compression bring it down.
- I turned a PDF price table into an image but the small numbers blur when zoomed in; how do I fix it?Fine print gets very few pixels at 72 or 96 DPI, so it smears when customers zoom. Go to 200 or 300 DPI and choose PNG; the numbers below show why.
- Other converters list page 10 before page 2 in my folder; will these page images sort in the right order?Some tools name images p1, p10, p2, and the order breaks. Here the page number is zero padded to the document's page count, so images sort correctly anywhere.
- I want to turn the pages of a signed contract into images; does the site keep a copy of my file?The file is never sent to a server: it is read and drawn in your browser with pdf.js. What stays on your device afterwards, and what a contract loses as an image.
- If I turn my price list PDF into images, does that stop competitors copying the text?An image drops the text layer, so prices cannot be selected and pasted, but anyone can still retype them or run OCR. It is a small hurdle, not protection.
- Will landscape or rotated pages in my PDF come out sideways as images?The rotation stored in the file is applied before the size is worked out, so images match what your PDF reader shows. And what to do if a page is sideways there too.
- My PDF mixes A4 and A3 pages; why do the images come out at different sizes?DPI is applied to each page's real size, so an A3 page yields a bigger image than an A4 page at the same setting. How to read the size groups, and how to match them.
- How do I put a PDF page into a PowerPoint slide as a crisp picture?Convert the page to PNG at 150 to 200 DPI and insert it as a picture. Why a slide needs fewer pixels than you think, and why PNG is better for text.
- I sell a PDF e-book in my online store; how do I turn its first page into a cover image for the product listing?Selling an e-book or guide as a PDF? Turn its first page into a JPEG for the product listing, then fit its shape and weight to your store theme.
- What JPEG quality should I pick when turning a restaurant menu PDF into a light but clear image?DPI sets how many pixels there are; JPEG quality sets how hard they are squeezed. Start at 150 DPI and quality 80 to 85, then compare two versions of the same page.
