Batch TIFF to PNG conversion is the same as single-file conversion — just drop multiple files at once. The tool processes each file sequentially in your browser, producing lossless PNG output for every TIFF. No upload, no limit on file count, download as a zip when done.
How to batch convert TIFF files to PNG
- Open the converter at the top of this page.
- Drag all your .tiff files into the drop zone at once, or click to open the file picker and select multiple files (hold Shift or Ctrl/Cmd to multi-select).
- Click Convert. The converter processes files one by one in your browser.
- When complete, download each file individually or click "Download All" to get a zip with all PNGs.
Unlike TIFF-to-JPG conversion, there's no quality setting to choose for TIFF-to-PNG because PNG is always lossless. The output quality is determined by the input — every PNG will be a perfect copy of the corresponding TIFF.
For a batch of 20 TIFF files at 30MB each, expect 2–5 minutes total on a modern laptop. The conversion runs in your browser using local processing — no files leave your device.

There's no hard file count limit built into the tool. The practical limit is your device's available RAM, since each TIFF needs to be decoded and held in memory during conversion.
Rough guidelines:
- Desktop or laptop with 16GB+ RAM: 50–100 files comfortably at 30–50MB each.
- Laptop with 8GB RAM: 20–30 files at 30–50MB each without slowdown.
- 4GB RAM device: 10–15 files before the browser starts to slow.
If your batch is very large (100+ files), split it into groups of 30–50 and run in multiple sessions. The browser's memory clears between sessions. There's no limit on how many sessions you can run.
For larger batch workflows and format flexibility, the batch image conversion guide covers tools and strategies for very large batches.
What to expect for PNG file sizes in a batch
PNG is lossless but not as small as JPG. Expect these rough size relationships in a batch conversion:
| Original TIFF size | Expected PNG size | Ratio |
|---|---|---|
| 100MB uncompressed TIFF | 20–50MB PNG | 2–5x smaller |
| 30MB LZW-compressed TIFF | 20–28MB PNG | ~1.2x smaller |
| 5MB scanned document TIFF | 1–3MB PNG | 2–5x smaller |
| 200MB high-res photography TIFF | 50–100MB PNG | 2–4x smaller |
If storage space is the priority and lossless quality isn't required, converting to JPG instead produces files 10–30x smaller. The batch TIFF to JPG guide covers that path.
PNG is the right batch output when transparency is needed, images contain text or sharp graphics, or further editing of the output files is planned.

Will all my TIFF files produce lossless PNG output in a batch?
Yes. Every file in the batch gets the same lossless treatment. The PNG output for each TIFF is a pixel-perfect copy of the input — no file in the batch will lose quality.
Can I batch convert TIFF files that have different dimensions and resolutions?
Yes. Each file is processed independently. A batch can contain TIFFs of different sizes, resolutions, color spaces (RGB, CMYK, grayscale), and even different TIFF compression types. Each produces a valid PNG output at its own native dimensions.
