Is this PNG 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 PNG 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.

Both PNG and TIFF are lossless — why convert?

Software compatibility. Professional print tools (Adobe InDesign, RIP software, commercial printers) expect TIFF. Scientific imaging software often only reads TIFF. The pixel data is identical; only the container changes.

Will the TIFF file be larger than the PNG?

Usually yes. PNG uses lossless deflate compression that is very efficient. TIFF can be uncompressed or use LZW/ZIP compression; our output uses LZW, which is slightly less compact than PNG's deflate for most images.

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.

How to convert PNG to TIFF online

1
Drop your PNG file
Drag and drop your Portable Network Graphics file onto the converter, or click to browse your files. You can select up to 5 at once. Nothing leaves your device — conversion happens right here in the browser.
2
Hit Convert — it happens locally
Click Convert and watch it go. There's no upload, no server queue, no waiting. The converter runs Portable Network Graphics → Tagged Image File Format entirely in your browser tab. Most files finish in 1–3 seconds.
3
Download your TIFF
Your Tagged Image File Format file is ready. Click Download, or grab a ZIP if you converted a batch. Close the tab and everything disappears — no copies kept anywhere.

Why convert PNG to TIFF?

PNG is lossless and excellent for web use, but many professional print and imaging workflows expect TIFF. The two formats share lossless quality, but TIFF carries metadata capabilities and format conventions that are standard in print production, scientific publishing, and document management systems that PNG simply doesn't have.

Adobe InDesign, professional print-house RIP software, and many archival imaging systems specify TIFF as the required input format. Medical imaging workflows, GIS platforms, and multi-page document scanners all use TIFF as their native format. Some of these systems will accept PNG, but others reject it at the file-type validation step before the image is even opened. Converting PNG to TIFF resolves those rejections without any quality loss.

Because both formats are lossless, the pixel data is preserved identically — there's no quality difference between the source PNG and the resulting TIFF. The TIFF will typically be larger than the PNG because TIFF's compression (LZW or ZIP) is generally less efficient than PNG's compression for most image types. Expect the TIFF to be 10–30% larger than the source PNG, depending on image content. If you're converting for print, make sure the resolution metadata (DPI) is correct in the source file — conversion preserves whatever DPI is set in the PNG.

Quality & file size: PNG to TIFF

Typical file sizes: PNG 8–25 MB → TIFF 20–70 MB.

Both PNG and TIFF use lossless compression, so no quality is lost in conversion. The output TIFF file will be visually identical to the PNG source.

Color depth: PNG supports 16-bit, TIFF supports 32-bit.

Transparency: PNG supports transparency. TIFF preserves transparency.

Privacy: how FormatDrop handles your files

Your PNGfiles 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.
