Convert PNG to TIFF

uncompressed RGB / RGBA · little-endian · batch · nothing uploaded

Print shops, journals and archival systems still ask for TIFF. Drop your PNGs and get valid uncompressed TIFF files back, written directly in your browser — no upload, no watermark, no account.

    What gets written

    A little-endian (II) TIFF with a single uncompressed strip: Compression=1, PhotometricInterpretation=2 (RGB), 8 bits per sample, chunky planar layout, and a 72 dpi resolution pair. With the alpha box ticked you get four samples per pixel and an ExtraSamples=2 tag marking the fourth as unassociated alpha, which is what Photoshop, GIMP, ImageMagick and libtiff expect. Untick it and transparency is composited onto your flatten colour and three samples are written.

    Uncompressed is deliberate. It's the variant nothing rejects. The cost is size — roughly width × height × 3 or 4 bytes — so a 4000×3000 photo lands near 48 MB. Any TIFF-capable tool can re-save it with LZW or Deflate compression in one step if you need that.

    About dpi and print size

    The file is tagged 72 dpi because that's what a screen-origin PNG honestly is. Physical print size comes from pixels ÷ dpi, so a 3000-pixel-wide image is 10 inches at 300 dpi. If your printer asked for a specific dpi tag, set it on the source with Change PNG dpi first, or let their prepress software set it — the pixels are what matter.

    FAQ

    Is any quality lost?

    No. Uncompressed TIFF stores the exact pixels from the PNG. The only change is transparency flattening, and only when you turn alpha off.

    Will this open in Photoshop / GIMP / Preview?

    Yes — it's a standard baseline TIFF. If a niche tool complains, try unticking alpha; a few older readers only handle three-sample RGB.

    Can I get CMYK TIFF for print?

    No. Proper CMYK conversion needs an ICC profile and a rendering intent, which is a prepress decision rather than a pixel operation. Send RGB and let the printer separate it. For a rough look at the separations, PNG to CMYK splits the channels as grayscale images.

    Can it make a multi-page TIFF?

    Not currently — each input becomes its own single-page file. For a multi-page document from several images, PNG to PDF is usually what people actually want.
