HEIC to PDF, batch of 20. Nothing ever uploads.

Yes, a little — and the page is honest about it. HEIC itself is a lossy format, so detail it discarded is gone before this tool starts, and the PDF re-encodes each photo as a JPEG at the quality you pick (90 by default). At quality 90 the loss is invisible in normal viewing and printing; drop the slider towards 50 for smaller files and you will start to see JPEG artefacts in smooth skies and gradients. The PDF can never be higher quality than the HEIC it came from.

Your choice. Per photo (the default) makes one PDF per HEIC, each named after its photo, with a Download all as ZIP button for the whole batch. Combined puts every photo on its own page, in list order, in a single PDF — the right pick for a set of photos going to one form, email or print job. You can reorder files with the ↑ / ↓ buttons before converting; combined mode follows that order.

Original photo size makes each page exactly the size of its photo (1 pixel = 1 point) — best when the PDF is read on screen and page size does not matter. A4 is the safe default for forms and printing in the UK and Europe; Letter matches US forms. Fit keeps the whole photo visible, centred, with its aspect ratio kept and never upscaled; Fill scales the photo to cover the whole page and crops the overflow, and may enlarge a small photo to do it — use it only when every page must be edge-to-edge. Photos are never distorted.

Yes. iPhones store most photos sideways with an EXIF orientation tag that says how to rotate them, and this tool reads that tag and applies it, so the PDF page shows the photo upright. All eight EXIF orientations are handled, including mirrored ones. The photo itself is never modified — only the PDF page is rotated.

Only the first still goes into the PDF. A Live Photo or burst is a container holding several stills (plus a short video), and a PDF page holds one still image, so the first still is converted and the rest are not included. If you need a different frame, export that still from Photos first and convert it on its own.

No. The PDF is a fixed-layout document whose pages hold pictures, not text — there is no text layer, so the PDF is not searchable and you cannot select or copy words from it. If you need searchable text, run the PDF through OCR afterwards.

No. Your photos are decoded and turned into a PDF entirely in your browser — your file data never leaves the device, and the only third-party requests are the site's own analytics, which count page views. You can verify it yourself with the network-request counter in the privacy section below the converter.

No. There is no daily limit and no account. A 25 MB safety cap applies per file and 20 files per batch, because decoding very large HEICs in the browser is memory-heavy. Most iPhone photos are 2–5 MB, far below the cap.

HEIC compresses far better than JPEG, and this tool re-encodes each photo as a JPEG for the PDF — so the same picture takes more bytes as a JPEG than it did as a HEIC, plus a small page wrapper per PDF page. A 3 MB HEIC typically becomes a 4–6 MB PDF page at quality 90. That is the format, not a failure — and lowering the quality slider shrinks the PDF.

A 10-bit HEIC folds to 8-bit colour in the PDF — the decode path works in 8 bits per channel, a precision change you cannot see on screen or in print. Transparency, rare in HEIC, is flattened onto the background colour you pick in the settings, because JPEG has no alpha channel. All other EXIF and metadata — location, camera settings, timestamps — is dropped; only the orientation is read and applied.
