How to Convert PDF to JPG or PNG (and Back)
Converting goes both ways depending on what you're starting with: turning PDF pages into images so you can post them, edit them, or insert them into a slide deck — or turning a stack of photos and screenshots into a single PDF for submission. This guide covers both directions, which format to pick, and what resolution actually means for your result.
PDF to JPG or PNG — Step by Step
Open the PDF to Image Tool
Go to shrinkpdf.fyi/pdf-to-images.html. No sign-up required.
Upload Your PDF
Click Choose PDF File or drag and drop.
Choose Format and Resolution
Pick JPG or PNG, then choose 72, 150, or 300 DPI depending on what you'll use the images for (see the DPI section below).
Convert and Download
Click Convert. Each page is rendered as a separate image. For a single page, download it directly; for multiple pages, download all of them together as a ZIP.
JPG vs PNG — Which Should You Choose?
Use JPG for photos, scans, and documents you want to share on WhatsApp, by email, or upload to a portal with a size limit. JPG compresses the image data, which makes files significantly smaller — usually the right tradeoff unless you specifically need pixel-perfect output.
Use PNG when you need exact, lossless quality — a document with very fine text, sharp diagrams, screenshots, or anything with a transparent background. PNG doesn't lose any detail in the conversion, but the files are noticeably larger than the equivalent JPG.
If you're not sure which to pick, JPG is the right default for most real-world sharing and submission scenarios.
What Resolution (DPI) Actually Means
DPI (dots per inch) controls how many pixels are rendered per inch of the original page — higher DPI means a sharper, larger image file.
| 72 DPI | Screen only — smallest files, fine for viewing on a phone or computer screen, not for printing |
| 150 DPI | Standard — the default for most uses: sharing, presentations, general printing |
| 300 DPI | High quality — for printing where fine detail matters; files are considerably larger |
One thing DPI can't fix: if the source PDF itself was already low-resolution (a blurry scan, for instance), converting at 300 DPI won't add detail that wasn't in the original — you'll just get a larger file of the same blurry image.
JPG or PNG to PDF — Step by Step
Open the Image to PDF Tool
Upload Your Images
Click Choose Images or drag and drop. JPG, PNG, and WEBP are all supported, and you can mix formats in the same conversion — there's no limit on how many images you add.
Reorder if Needed
Drag images into the order you want them to appear as pages in the final PDF.
Convert and Download
Click Convert. Each image becomes one page in a single PDF, downloaded straight to your device.
JPG and PNG images are embedded at their original resolution with no quality loss. PNG transparency carries over into the PDF correctly. WEBP is the one exception: it's converted to JPEG internally before being embedded, so a transparent background in a WEBP file will not stay transparent in the output — if transparency matters, convert that image to PNG first.
Common Conversion Scenarios
Some platforms don't accept PDF uploads directly — convert the relevant page to JPG first.
PowerPoint, Google Slides, and Word all accept images directly, but not PDFs. Convert the page you need to PNG for the sharpest result if it contains text or diagrams.
If you photographed several pages of a form with your phone, convert all the photos into one PDF instead of sending separate image files — most portals expect a single PDF, not a folder of JPGs.
