Is this HEIC to PDF converter really free?

Yes. Up to 5 files at a time, no signup, no catch. The free tier adds a small watermark to image output — Pro ($9.99/mo or $49/yr) removes it, raises the file size limit to 500 MB, and unlocks unlimited batch conversion.

Are my files uploaded to a server?

No — and you can verify it yourself. Open DevTools → Network tab, then convert a file. You'll see zero upload requests. Everything runs right in your browser. We never see your files.

How long does conversion take?

Usually 1–3 seconds for a typical file. The very first conversion on a fresh page load may take 5–20 seconds while the converter engine loads — after that it's instant. Your CPU does all the work locally.

What is the file size limit?

Free: up to 10 MB per file, 5 files per batch. Pro: up to 500 MB per file, unlimited batch. If you're working with large videos or RAW photos, Pro is built for that.

Can I batch convert multiple HEIC files at once?

Yes — drop multiple files at once (or Ctrl/Cmd+click to select them) and they all convert in parallel. Free accounts handle up to 5 files per batch; Pro has no limit.

Will my document formatting survive conversion?

Standard formatting — text, headings, bold/italic, tables, and inline images — transfers reliably. Complex layouts with floating objects, custom fonts, or SmartArt may simplify. Always give the output a quick review before sharing.

Can I convert a password-protected document?

No — encrypted files can't be read without decryption, and we never ask for passwords. Remove the password protection first, then convert.

Can I combine multiple HEIC photos into one PDF?

Yes — select multiple HEIC files and each becomes a page in the resulting PDF, in selection order. Useful for sending several photos as a single document for insurance claims, rental applications, or form submissions.

Will HEIC metadata like GPS location appear in the PDF?

No. PDF doesn't carry image EXIF metadata in the same way. GPS location, camera model, and capture settings embedded in the HEIC are stripped during the conversion.

How private is this converter?

Completely private — by design, not policy. There is no upload endpoint. Files are processed right inside your browser tab and disappear the moment you close it. We collect only anonymous page-view counts; your file content is never seen or stored.

Why convert HEIC to PDF?

When you take photos on an iPhone, they are saved as HEIC files — Apple's default format since iOS 11. That is fine for your camera roll, but the moment you need to submit those photos somewhere — an insurance claim, a property damage report, a medical intake form, a rental application — HEIC becomes a problem. Most submission portals, government forms, and email recipients on Windows machines cannot open HEIC files without installing extra software they do not have.

Converting multiple HEIC photos to a single PDF solves this in one step. The recipient gets one file, one attachment, one document they can open in Adobe Acrobat Reader, Preview, Microsoft Edge, or any browser — no installation required. PDF is the standard format for document submissions precisely because it renders identically everywhere. For insurance adjusters, property managers, lawyers, and healthcare administrators, a multi-page PDF is the expected deliverable.

Each HEIC image becomes one page in the PDF, sized to fit standard paper dimensions. The photos are embedded at high resolution, so fine detail — like a crack in a wall or text on a document — remains legible when zoomed in. File size grows proportionally with the number of images and their resolution, so a batch of ten iPhone photos typically produces a PDF between 5 and 25 MB depending on image content. For submission by email, keep batches to 5-10 photos to stay under typical attachment limits.

Quality & file size: HEIC to PDF

Typical file sizes: HEIC 1.5–3 MB → PDF 100–500 KB.

Converting from lossy HEIC to lossless PDF will not recover detail the HEIC codec already discarded — but the output will not degrade any further. This is useful when you need a lossless format for editing or compatibility without additional compression artifacts.

Color depth: HEIC supports 12-bit, PDF supports standard color.

Transparency: HEIC supports transparency. PDF does not support transparency — transparent areas become solid white.

Your HEIC files are converted 100% inside your browser. They are never uploaded to our servers, never stored, and never seen by anyone other than you. This isn't a privacy policy claim — it's an architectural guarantee: our server has no endpoint that receives file bytes.
