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.
HEIC to PDF online with ImgShifter
iPhones have shot HEIC by default since iOS 11 in 2017, and almost nothing in the PDF world reads it - which is why bundling iPhone photos into a document usually means a clumsy HEIC-to-JPG detour first. This tool removes the detour. Drop .heic or .heif files straight from your Camera Roll, AirDrop, or Files app, arrange them, and build a PDF in one pass. No intermediate JPGs cluttering your downloads folder.
Each HEIC is decoded on-device by a WebAssembly module that downloads once and then caches for offline use, and embedded into the PDF as JPG at 92% quality - visually lossless for photos, and about the same size you'd get converting to JPG by hand. It's the natural tool for turning a batch of photographed receipts, scanned documents, or a trip's worth of shots into a single file you can send. Page sizes are A4, Letter, or Match; reorder pages in the thumbnail strip before you build.
Nothing uploads. The HEIC decode, the jsPDF assembly, and the download all happen in your browser - so it works directly in iPhone Safari, picking photos from the Photos sheet, with the whole process staying on the phone. Check the Network tab for zero outbound traffic, or go offline after the page loads and it still builds.
