How do I convert HEIC to PDF?

Add your HEIC file to the upload area above, then press Convert. The PDF file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to PDF reduce quality?

No. PDF is a lossless format, so the conversion preserves exactly what is in your HEIC file. Note that it cannot recover detail that was already discarded when the HEIC was first created — a lossless container does not undo earlier compression.

How large a file can I convert?

Up to 120 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

HEIC and PDF explained

HEIC is the container Apple uses for photos taken on iPhone since iOS 11, holding images compressed with HEVC. It stores roughly the same visual quality as JPEG in about half the space, and can hold extras such as depth maps and Live Photo frames.

PDF describes a page as a fixed arrangement of text, vector graphics and images. Unlike a word processor document, it is designed so the page looks identical everywhere — which is exactly why it is awkward to edit.

Where HEIC files come from: Every iPhone photo taken since 2017, unless the camera format was changed to “Most Compatible”.
Where PDF is used: Contracts, invoices, reports, forms, academic papers and scanned documents.

HEIC vs PDF

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

HEIC compared with PDF
Property	Source	Target
Compression	Lossy	Lossy or lossless
Transparency	Yes	—
Animation	Yes	—
Introduced	2015	1993
Browser support	Apple platforms. Poor support elsewhere — convert to share.	Universal.

HEIC is stronger at: About half the file size of JPEG at similar quality. Supports 16-bit colour, so gradients band less than in JPEG. Can store transparency, depth data and image sequences.
PDF is stronger at: Looks identical on every device, in every viewer, when printed. Supports digital signatures, forms and embedded fonts. Universally readable without special software.

Why convert HEIC to PDF?

Converting HEIC images to PDF packages them into a single paginated document. That matters when you are submitting scans, assembling receipts, or sending several images to someone who should receive one file rather than an inbox full of attachments.

HEIC limitations that prompt the switch: Poor support outside Apple platforms — Windows needs a paid codec, many web apps reject it. Encumbered by HEVC patent licensing, which is why adoption stalled. Older Android devices cannot open it at all.
What you give up: Genuinely hard to edit — it stores positioned glyphs, not paragraphs. Scanned PDFs contain no text at all until OCR is run.

Does converting HEIC to PDF reduce quality?

Both formats store the content without discarding data, so this conversion preserves it exactly. The file size may change because the two formats compress differently, but the content itself is unaffected.

HEIC is not an Apple-invented format. It is the MPEG HEIF standard; Apple simply shipped it first and at scale.

A PDF full of scanned pages is a stack of pictures, not a document. Selecting text is impossible until OCR has been run over it.
