Convert HEIC to PDF — Free, Fast & Private
The heic to pdf conversion solves two problems in one pass. iPhones have saved photos as HEIC by default since iOS 11, and almost nothing outside the Apple ecosystem opens them — not Windows without extra codecs, not most upload portals, not the person you emailed them to. PDF has the opposite reputation: it opens identically on every device made this century. Converting HEIC photos straight to PDF skips the intermediate JPG step entirely and produces a single document ready for applications, records, and printing.
Select the Image → PDF tab in the tool above, drop in your HEIC photos, and click Create PDF. MiniPx decodes HEIC in the browser — Chrome, Firefox, Edge, and Safari all work, with no app or codec pack to install — and assembles the pages with jsPDF, also in the browser. Your photos never leave your device, which matters more than usual here: the things people turn into PDFs are IDs, medical records, signed forms, and receipts.
Each photo can be up to 200 MB, and there is no daily or monthly quota. Images too large to decode safely in a browser tab are skipped with a note rather than failing the whole batch.
Why HEIC photos are awkward to submit anywhere
HEIC compresses with the patented HEVC codec, so support outside Apple devices is spotty: Windows needs a paid extension from the Microsoft Store, many web forms reject the extension outright, and document portals that accept "photos of your documents" usually mean JPG or PDF. That leaves iPhone users stuck exactly when the stakes are highest — visa applications, job applications, university admissions, insurance claims. A PDF sidesteps every one of those rejections at once, and unlike a loose folder of images, it holds multiple photos in a fixed order as one attachment.
Combine many iPhone photos into one PDF
Each photo becomes exactly one page, and pages follow your upload order — so add the photos in the sequence you want them read. This is the natural way to package a multi-page paper document you photographed with your phone: front and back of an ID, a several-page contract, a stack of receipts for an expense report. The output is a single PDF you can name, attach, and send, instead of six image files that arrive in whatever order the recipient's client sorts them.
Order matters most for anything a reviewer reads top to bottom, so it is worth a few seconds of planning before you drop the files in. If a batch comes out in the wrong sequence, clear it and re-add the photos in the right one — with everything running locally, a redo costs seconds rather than another round trip to a server queue.
How pages are sized: no forced A4, no margins
By default MiniPx sizes each PDF page to its photo's own pixel dimensions rather than forcing everything onto A4 or Letter with white borders. The photo fills the page edge to edge, and orientation is handled per photo — a landscape shot gets a landscape page, a portrait shot a portrait page, automatically, even within the same document. Nothing is cropped, squeezed, or letterboxed. When you print, your PDF viewer's standard fit-to-page option maps each page onto the paper size you choose.
That default is right for photographs and wrong for paperwork that will be checked rather than looked at, so the Page size control offers A4 and US Letter as well. Choose one and every page gets exactly that page box — 595 by 842 points for A4, 612 by 792 for US Letter — turned to landscape when the photo is landscape, with the photo scaled to fit inside it and centred. Nothing is cropped there either; a photo of a different shape simply leaves a white margin. It is the option to take when a portal validates the page size, when a print shop prices by the sheet, or when the document has to print at actual size instead of fit-to-page.
Private by design
Most online HEIC to PDF converters are upload services: your photos travel to a server, get processed, and sit there under a retention policy you have to take on faith. MiniPx's architecture makes that concern moot — the HEIC decoder and the PDF builder both run inside your browser tab, so there is no server-side copy to worry about. For passports, ID photos, financial paperwork, and anything else you would rather not hand to an unknown host, that is the whole argument.
When an image format is the better target
PDF is for documents; it is not the right container for photos you want to keep editing or post online. If the destination is a photo library, an editor, or a website upload field that wants an image, convert to JPG for universal compatibility or WebP for the web. For the reverse trip — pulling pages back out of a PDF as images — use PDF to Image, and for shrinking a finished scan there is a PDF size guide.
