Is this HEIC to TIFF 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 the image quality change after conversion?

It depends on the formats involved. Converting to a lossless format like PNG preserves every pixel exactly. Converting to a lossy format like JPEG or WebP applies compression — we default to 85% quality, which looks identical to the original for almost all images. You won't notice a difference unless you zoom in pixel-by-pixel.

Do you support batch image conversion?

Yes — drop multiple images at once and they all convert in parallel. Free accounts handle up to 5 at a time; Pro is unlimited. Download everything as a single ZIP when you're done.

Is TIFF output from HEIC truly lossless?

Yes — TIFF stores all decoded pixel data without additional compression. The quality matches what was inside the HEIC file; no further information is lost in the conversion.

What's the difference between converting HEIC to TIFF vs PNG?

Both are lossless. TIFF is preferred in professional print, archival, and CMYK workflows; PNG is better for web use and general editing. For sending to a print lab or archive drive, TIFF is the conventional choice.

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 TIFF?

HEIC photos from iPhone look excellent on Apple devices, but professional workflows — print houses, photo labs, archival systems, and scientific imaging platforms — often require TIFF as the delivery format. HEIC is a consumer camera format; TIFF is what professionals use when quality and compatibility with editing software both matter.

TIFF is the standard input format for print-ready workflows in Adobe InDesign, professional scanners, and archival databases. Major photo editors like Photoshop and Lightroom can export to TIFF with full layer support, but they need a TIFF to work with when interoperating with other tools. If you're sending images to a print lab, a magazine, or a medical imaging system, TIFF is the format they expect. It's also the best format for multi-page document scans and high-resolution artwork.

Converting HEIC to TIFF gives you a lossless result — the pixel data is preserved without any compression artifacts. File sizes will be substantially larger than the original HEIC: a 4 MB HEIC photo may become a 20–40 MB TIFF. That's expected and appropriate for archival or print use. If you just need to share the photo or post it online, convert to JPEG instead — TIFF is for workflows where quality cannot be compromised.

Quality & file size: HEIC to TIFF

Typical file sizes: HEIC 1.5–3 MB → TIFF 20–70 MB.

Converting from lossy HEIC to lossless TIFF 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, TIFF supports 32-bit.

Transparency: HEIC supports transparency. TIFF preserves transparency.

Privacy: how FormatDrop handles your files

Your HEICfiles 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.
