Useful to know
How combining works
Drop one or many images, drag the thumbnails in the file strip to set the page order, pick a page size, and click Build PDF. Each image becomes one page in the PDF. With 'Combine into one PDF' on (the default), you get a single multi-page PDF. With it off, each image becomes its own PDF and the set is bundled into a ZIP.
A4 / Letter / Match the image
A4 (210 x 297 mm) is the default and the right pick for printable documents. Letter (216 x 279 mm) matches US standard paper. Match sizes each page to the source image's pixel dimensions exactly - useful for screenshots and scans where you want no white bars and no cropping. For A4 and Letter, the fit mode toggle controls whether the image is contained (whole image visible, may leave white bars) or covers the page (fills the page, may crop edges).
iPhone HEIC support
Drop .heic or .heif files straight from your iPhone Camera Roll, AirDrop, or Files app. ImgShifter decodes each HEIC locally in your browser using a WebAssembly module before adding it to the PDF. The final PDF is a standard JPG-backed PDF that opens anywhere - no separate HEIC-to-JPG conversion step.
Privacy (no upload)
The PDF is assembled entirely in your browser using jsPDF. Images are decoded locally, embedded in memory, and the PDF is saved to your downloads folder. You can verify by opening DevTools Network tab while you build (zero outbound traffic) or by going offline after the page loads.
When to use this vs compress/crop first
If you want a smaller PDF, compress the images first with the compress tool, then drop the compressed JPGs into the PDF builder. If you want to remove edges or change aspect ratios, crop first. The PDF builder is the assembly step - it works best on images that are already at the size and quality you want for the final document.
PNG to PDF online with ImgShifter
The job this tool does most is stitching screenshots into a single PDF - app captures, web clippings, scanned pages, design proofs. Drop your PNGs, drag them into reading order in the numbered strip, and build a multi-page PDF where each screenshot is its own page. Flip the combine toggle off and you get one PDF per PNG instead, bundled in a ZIP.
PNG's defining feature - transparency - doesn't map onto PDF, which expects opaque pages, so any transparent areas are flattened to white before embedding. That's what virtually every PDF viewer expects and what you want for screenshots and documents. The pixel data itself goes in at full resolution, so text and UI stay crisp even when a reader zooms in. For screenshots, the Match page size is usually the right call: the page mirrors the PNG's exact dimensions with no cropping and no white bars.
It's all browser-side via jsPDF - PNGs are decoded locally, flattened, embedded in memory, and the finished PDF saves straight to your downloads. No upload, no signup, no watermark, no rate limit. Confirm there's no outbound traffic in the DevTools Network tab, or just pull the network after the page loads and keep building.
