TIFF to PNG Converter

Re-encode lossless TIFF scans into web-ready PNGs (alpha and 16-bit depth intact) without a single byte leaving your machine.

What it does

  • Lossless TIFF/TIF to PNG entirely in your browser tab — no upload, no server, no account
  • Preserves an RGBA TIFF's transparency and high-bit-depth (up to 16-bit) channels
  • Batch convert dozens or hundreds of scans; multiple outputs download as a ZIP
  • Splits a multipage TIFF into one PNG per page instead of dropping all but the first

PNG, JPG, WebP, BMP, TIFF, or AVIF

TIFF to PNG conversion turns a TIFF into a web-friendly PNG without uploading anything, because the file is read and re-encoded right inside your browser tab. People reach for this because TIFF simply will not display in most browsers, email clients, Slack, Discord, or a CMS, while PNG renders everywhere. TIFF users care about quality and reject JPG, so they want a lossless target, transparency kept if the file has an alpha channel, and often a whole folder of scans (legal, medical, GIS, microscopy, archival) converted at once while the original bytes stay on the machine.

What this conversion actually does (and does NOT do)

Both TIFF and PNG are lossless raster formats, so this is a re-encode, not a recompression. Unlike TIFF to JPG, no image quality is lost: every pixel that was in the TIFF is in the PNG. That is the key reason TIFF users prefer PNG over JPG as a sharing derivative.

The file usually gets smaller, not larger. PNG's DEFLATE filtering compresses both photographic and flat-color data more efficiently than baseline uncompressed or LZW TIFF, so a TIFF in the 5-25MB range commonly lands in the low single-digit MB as a PNG at the same resolution and the same quality. You are trimming container overhead, not throwing away detail.

Transparency is preserved when the source has it. PNG supports the same RGBA model as TIFF, so an RGBA TIFF maps cleanly to a transparent PNG, and PNG can carry up to 16 bits per channel. That last point is the counterintuitive one: a 16-bit scientific, medical, or HDR-scan TIFF does NOT get truncated to 8-bit the way it would in many other formats, because PNG can hold the full bit depth.

Two things change. First, multipage: PNG cannot store multiple pages, so a multipage TIFF (common from document and fax scanners) must be split into one PNG per page. Many tools silently export only the first page; the converter here produces every page. Second, color model: TIFF can be CMYK and carry many private tags, but PNG is always RGB or grayscale, so a CMYK TIFF is converted to RGB and not every TIFF tag necessarily survives, though PNG can embed an ICC profile (iCCP) to keep color accurate.

When to choose TIFF to PNG vs the alternative

Choose PNG when you need a lossless, browser-ready copy: line art, screenshots, documents, diagnostic images, or anything where exact pixels and transparency matter. PNG keeps the alpha channel and the full bit depth, so it is the right target when fidelity is the point. Choose JPG instead only when the image is a photograph you are sharing casually and small size beats perfect fidelity, since JPEG (also written JPG) is lossy and flattens transparency against a solid background. If that tradeoff fits, use TIFF to JPG; otherwise stay with PNG here to keep transparency and lossless quality.

How to convert

  1. Drop one or many TIFF/TIF images into the converter; they are read locally, never uploaded.
  2. The output format is pre-selected to PNG. PNG is lossless, so there is no quality slider to set — every pixel is preserved.
  3. If a TIFF has an alpha channel it is kept as transparency; a multipage TIFF is split into one PNG per page automatically.
  4. Click Convert. A single file downloads directly; multiple files (or one PNG per page) download together as a ZIP, with no count cap.

No upload. It runs on your device.

The conversion engine is Rust compiled to WebAssembly, running inside your browser tab. When you drop a TIFF, the bytes are decoded and re-encoded in local memory, so there are zero network requests for the file itself. After the page has loaded once it works fully offline, on an airplane or an airgapped machine, and there is nothing to delete afterward because nothing was ever uploaded. You can verify this yourself: open your browser DevTools, watch the Network tab while you convert, and you will see no file leave the device. This matters because TIFF is the format of choice for genuinely sensitive material, scanned legal and discovery records, medical and diagnostic imaging, ID documents, and archival government files, none of which belongs on a stranger's server even briefly.

No limits

Convert unlimited batches with no file-count cap and no server-imposed size limit. There is no watermark stamped on output, no sign-up, and no ads.

Frequently asked questions

Does converting TIFF to PNG lose quality?
No. Both TIFF and PNG are lossless raster formats, so the conversion is a re-encode that keeps every pixel, unlike TIFF to JPG which discards data. The image you get back is pixel-identical to the source TIFF at the same resolution.
Is TIFF to PNG conversion lossless?
Yes, it is fully lossless because neither format throws away image data during encoding. PNG uses DEFLATE compression, which reduces file size without altering any pixel values, so nothing is approximated or degraded.
Will the transparency in my TIFF be preserved as a PNG?
Yes. PNG supports the same RGBA model as TIFF, so an RGBA TIFF maps cleanly to a transparent PNG with its alpha channel intact. This is the main reason to choose PNG over JPG, which has no alpha and would flatten transparency against a solid background.
Why is my PNG smaller than the original TIFF?
PNG's DEFLATE filtering compresses photographic and flat-color data more efficiently than uncompressed or LZW-packed baseline TIFF. A TIFF of 5-25MB commonly becomes a PNG in the low single-digit MB range at the same resolution, and because the conversion is lossless that smaller size costs you nothing in quality.
How do I convert a multipage TIFF to PNG?
PNG cannot store more than one page, so a multipage TIFF (common from document and fax scanners) is split into one PNG per page. The converter here produces every page rather than silently exporting only the first, and the resulting PNGs download together as a ZIP.
Can I batch convert many TIFF files to PNG at once?
Yes. Drop a whole folder of TIFF scans and they are all converted in your browser, with no file-count cap and no daily quota. A single file downloads directly while multiple files arrive as a ZIP.
Are my files uploaded to a server when I convert TIFF to PNG here?
No. The converter is Rust compiled to WebAssembly running in your browser tab, so the TIFF is decoded and re-encoded in local memory with zero network requests for the file. You can confirm this in your browser DevTools Network tab, where you will see no file leave the device.
Can I convert TIFF to PNG offline or without internet?
Yes. Once the page has loaded once, the WebAssembly engine runs entirely client-side, so you can convert with the network off, on an airplane, or on an airgapped machine. Nothing about the conversion depends on a server round-trip.
Is there a file size or file count limit?
No. Because processing happens on your own device rather than a shared server, there is no imposed size cap and no maximum number of files. The practical limit is your machine's available memory, not a free-tier quota.
What happens to 16-bit or CMYK TIFFs when converted to PNG?
PNG supports up to 16 bits per channel, so a high-bit-depth scientific, medical, or HDR-scan TIFF converts without being truncated to 8-bit. CMYK is different: PNG is always RGB or grayscale, so a CMYK TIFF is converted to RGB during conversion, and PNG can embed an ICC profile (iCCP) to keep that color accurate.
Why won't my TIFF open in a browser but a PNG will?
TIFF is not natively rendered by most browsers, email clients, chat apps, or content management systems, which is the single most common reason people convert. PNG is rendered universally, so converting gives you a copy you can actually display, embed, and share.
