About the PDF Converter
PDFs and images often need to swap places — turning a PDF's pages into images to share or embed, or combining a set of images into a single PDF to send. The PDF converter does both in your browser using pdf.js and pdf-lib, with control over pages, resolution (DPI) and page size, and without uploading your documents.
Turning a PDF into images
Sometimes a PDF page is more useful as a picture — to embed a page in a slide or document, post a preview where a PDF viewer isn't available, or pull one figure out of a report. This converter renders pages to PNG or JPG, and you control the resolution up to 300 DPI: higher DPI means a sharper, larger image, which is worth it when there's small text or fine detail. You can export every page or just a range like "1-3, 5". A single page downloads as one image; several pages come back together in a ZIP.
Combining images into a PDF
The reverse is just as common: you have a set of photos or scans and need to send them as one tidy document rather than a pile of attachments. Add your images, choose how each page is sized — fit-to-image to match each picture exactly, or standard A4 / Letter pages for something printable — and they're combined into a single PDF in order. It's a quick way to bundle a multi-page scan, a receipt set, or a small portfolio.
Resolution, page size and privacy
A few choices shape the result. For PDF-to-image, match the DPI to the use: 150 DPI is fine for on-screen previews, while 300 DPI suits printing or reading dense text. For images-to-PDF, fit-to-image avoids empty margins, whereas A4 or Letter is better when the document will be printed. Everything is processed in your browser using pdf.js and pdf-lib, so even sensitive documents — contracts, IDs, financial statements — never leave your device. If the images you're combining are large, compressing them first with the image compressor keeps the final PDF a reasonable size.
Frequently asked questions
Can I convert a PDF to JPG or PNG?
Yes — render any or all pages to PNG or JPG at up to 300 DPI. A single page downloads as an image; several pages come back as a ZIP.
Can I turn images into a PDF?
Yes. Add multiple images and combine them into one PDF, either fit-to-image or on A4/Letter pages.
Which pages can I export?
All of them, or a specific range such as "1-3, 5".
Is my PDF uploaded to a server?
No. The PDF is processed entirely in your browser using pdf.js — it never leaves your device.
Can I convert just one page of a PDF to an image?
Yes. Enter a page range like "2" or "1-3, 5" and only those pages are rendered. A single page downloads as an image; several come back as a ZIP.
What DPI should I choose?
150 DPI is fine for on-screen previews; choose 300 DPI for printing or pages with small text. Higher DPI gives a sharper but larger image.
