Is this JPG 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 JPG 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.

Will converting JPG to TIFF make my image sharper?

No — the JPEG compression artifacts are already encoded in the source. TIFF stores the decoded pixels without further loss, but it cannot reconstruct detail the JPEG algorithm discarded.

My print lab requires TIFF. Can I use a JPG converted to TIFF?

Yes, as long as the source JPG is high enough resolution and quality. A high-quality JPG converted to TIFF will print well; a heavily-compressed JPG will show artifacts in print regardless of format.

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 JPG to TIFF?

JPEG works well for sharing photos online, but its lossy compression is a liability in professional workflows. Every time you save a JPEG, it re-compresses and loses a little more detail. For images going into print production, medical imaging systems, or archival storage, TIFF is the expected format because it preserves pixel data exactly.

Desktop publishing applications like Adobe InDesign, QuarkXPress, and professional print workflows default to TIFF for placed images. Photo labs that produce large-format prints often require TIFF files. Scientific journals and academic publishers frequently mandate TIFF at 300 DPI or higher for figures. Geospatial software like ArcGIS and QGIS also uses GeoTIFF (a TIFF variant) as its primary raster format.

One important caveat: converting JPEG to TIFF does not recover detail that JPEG compression already discarded. The TIFF will be losslessly encoded, but the starting point is the already-compressed JPEG data. If the JPEG has visible compression artifacts — blocky shadows, smeared edges — those will be preserved in the TIFF. The benefit is stopping further degradation: no more recompression cycles. File sizes will jump significantly — a 2 MB JPEG may become a 20–30 MB TIFF. That's the cost of lossless storage and print-quality compatibility.

Quality & file size: JPG to TIFF

Typical file sizes: JPG 2–5 MB → TIFF 20–70 MB.

Converting from lossy JPG to lossless TIFF will not recover detail the JPG 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: JPG supports 8-bit, TIFF supports 32-bit.

Transparency: JPG does not support transparency. TIFF preserves transparency.

Privacy: how FormatDrop handles your files

Your JPGfiles 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.
