Is this TIFF to PNG 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 TIFF 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.

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 TIFF to PNG?

If you've ever tried to open a TIFF file and hit a wall — the app won't accept it, the website rejects it, or the preview just shows a broken icon — you already know why this conversion matters.

Tagged Image File Format is great for what it was designed for, but it has real-world limitations: extremely large file sizes and not supported in web browsers natively. The moment you step outside that original context, it gets frustrating fast.

Portable Network Graphics is the safer choice for Logos and UI assets, Screenshots, Images requiring transparency. Its main advantages — lossless compression — pixel-perfect quality and full alpha transparency (8-bit alpha channel) — mean it just works wherever you need it.

A few common reasons people end up here: - Their target app, site, or device doesn't accept TIFF - They need a smaller file for email or upload (PNG often compresses better) - They need Portable Network Graphics's specific capability: lossless compression — pixel-perfect quality - Compatibility with older software that pre-dates Tagged Image File Format

The conversion is one-way: you get a PNG that works everywhere Portable Network Graphics is expected. The original TIFF file is not touched.

Quality & file size: TIFF to PNG

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

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