Image to PDF & PDF to Image Converter

Open the Image to PDF tool and select all your images at once - Ctrl-click in the file picker, or drag them in together. Pick page size (A4 or Letter for documents, Fit-to-image for galleries), orientation if relevant, and any margin you want. Confirm the order, since file pickers don't always respect your sort. Hit Generate, the tool creates a multi-page PDF with one image per page, and you download a single file. Useful for receipt batches, photo portfolios, ID document submissions or scan compilations from a phone camera.

Yes, switch to PDF-to-Image mode. The tool renders each PDF page as a PNG image and offers them for download, either individually or zipped. It's a render of the page, not necessarily extraction of the original embedded image. So if the PDF was built from a 4000px JPG but rendered at 144 DPI for an A4 page, you get the rendered version. Increase DPI to 300 or higher if you need print-quality output. For pulling out the actual embedded image objects untouched, a desktop tool like pdfimages from poppler-utils does that better.

Match the use case. 144 DPI (roughly 2x screen density) is fine for on-screen viewing, web posting, or quick reference - sharp enough on retina displays without huge files. 300 DPI is the print standard, what you want for documents going to a real printer. Anything above 600 DPI is overkill for most work and the file size balloons fast - a 10-page PDF at 600 DPI can hit 100MB easily. For archival scans of detailed documents, 400-450 DPI is a reasonable middle ground. Default to 144 for daily work, 300 when print quality matters.

Not necessarily. Most image-to-PDF tools embed JPGs and PNGs directly inside the PDF without re-encoding, meaning your originals are preserved byte-for-byte inside the PDF wrapper. The quality you perceive depends on how the PDF viewer scales those images to the page size. If you embed a 4000px image into an A4 page at 96 DPI, the viewer downscales for display but the original is intact at full resolution. If a tool re-encodes during embedding to shrink output size, that's where loss happens. Check whether your tool offers a preserve-original option.

If the tool provides drag-and-drop reordering, use it - that's the cleanest way. If not, the trick is to rename your source files with numeric prefixes before uploading: 01_cover.jpg, 02_intro.jpg, 03_main.jpg, and so on. The file picker selects them in alphabetical order, which then matches your intended sequence. Don't use 1, 2, 10 - use 01, 02, 10 with leading zeros, otherwise 10 sorts before 2 and you get a scrambled PDF. This trick saves a lot of time on batch jobs where you can't manually drag fifty images.

The PDF inherits whatever weight the source images carry. Five iPhone photos at 4-5MB each give you a 20-25MB PDF, no surprise. The PDF wrapper itself adds maybe a few KB - it's not the bottleneck. Pre-compress or resize your images before generating the PDF: drop dimensions to roughly 1500-2000px wide, JPG quality 80-85, and you'll typically cut total size by 70-80%. For document scans, switch to grayscale if color isn't needed. If the tool has a compress-on-output option, enable it. The fix is at the input stage, not the PDF stage.

With this tool, yes - everything happens in the browser. The images load into memory, the PDF gets assembled client-side using a JavaScript PDF library, and the file is offered as a download. No server upload, no third-party storage. Verify it yourself: open DevTools, watch the Network tab during conversion - you'll see no outgoing image traffic. That said, treat any online tool with caution if you can't confirm client-side processing. For sensitive material like IDs, contracts, medical records, prefer tools that explicitly say no-upload or use offline software like LibreOffice for full control.

Easy use case. Select your screenshots in the order you want them, set the page size to Fit-to-image so the PDF page matches the screenshot dimensions exactly without weird cropping or whitespace, and generate. A4 or Letter work too if you want a standard page format. The tool stitches the screenshots into sequential pages and outputs one PDF. Common applications: chat conversation exports, instruction sheets, bug report bundles, receipt archives. For phone screenshots specifically, Fit-to-image is usually what you want, otherwise tall screenshots end up shrunk awkwardly to fit A4 portrait.
