PNG to PDF converter

How to use the PNG to PDF converter

  1. Drop PNG or JPEG images into the upload zone, or click to pick files. Multiple images at once are welcomed.
  2. Drag the arrow buttons to reorder pages — the first image becomes page 1.
  3. Pick a page size (A4, Letter, Legal, A3, A5) or 'Auto' to size each page to its image.
  4. Set orientation, fit mode (contain to preserve aspect ratio, cover to fill, stretch to distort), and margin.
  5. Click 'Convert to PDF' — the file downloads instantly from your browser.

When to use it

Use it to bundle receipts, screenshots, scanned pages, or photo collections into a single shareable PDF. Converting in the browser is safer than uploading to a web service when the images are sensitive (medical, legal, ID documents). Alternative: ILovePDF and Smallpdf do the same thing online but require uploads and gate multi-page behind paywalls. This tool handles unlimited images and works offline after load.

Frequently asked questions

How do I convert PNG to PDF?
Drop your PNG files into the upload area, reorder them if needed, choose a page size, and click 'Convert to PDF'. The file downloads instantly — no sign-up, no watermark, no upload.
Is my PNG file uploaded to a server?
No. Conversion runs entirely in your browser using pdf-lib. Files never leave your device — a key difference from most online converters.
Can I combine multiple PNG images into one PDF?
Yes. Drop as many images as you want; the tool creates a multi-page PDF with one image per page, in the order you arrange them.
Does PNG to PDF work with JPEG images?
Yes — both PNG and JPEG are accepted. PNG preserves transparency (useful for logos); JPEG makes smaller files for photos.
What's the maximum file size?
There's no hard limit, but memory use scales with total image size. Tested smoothly with 50 images at 4MB each in Chrome. Very large batches (>200MB total) may slow down on low-RAM devices.
Can I set the PDF page size to match my images?
Yes — pick 'Auto' for page size. Each page becomes the exact dimensions of its source image at 72 DPI, plus the margin you set.
