TIFF is the workhorse format of scanners, fax systems, archives and print shops. It is reliable and flexible, but browsers can't display it and many apps, websites and upload forms won't accept it. When you need to view, share, edit or upload a TIFF, converting it is the fastest fix.
This converter turns TIFF and TIF files into lossless PNGs, so not a single pixel of your scan changes. Multi-page TIFFs are split into one PNG per page, transparency is kept, and everything runs in your browser without uploading your documents.
Before
TIFF, A4 scan at 300 dpi
≈ 25 MB (uncompressed)
Browsers, many apps and upload forms can't display it.
After
PNG, 2480 × 3508
≈ 1–10 MB
Every pixel kept; opens in every browser and app.
Typical for a full-colour A4 scan. PNG compresses losslessly, so text documents shrink a lot and detailed photos less. Black-and-white scans become much smaller.
Drop .tif or .tiff files into the workspace above, or click to choose them, up to 100 MB each.
PNG is preselected under Output format. Switch to JPG any time for smaller photo files.
Click Convert. Multi-page TIFFs produce one PNG per page, named page_1, page_2 and so on.
Save each PNG individually or download all pages and files in one ZIP.
| Content | Best output | Why |
|---|---|---|
| Scanned documents, forms, text | PNG | Lossless: text edges stay sharp |
| Line art, diagrams, logos | PNG | No JPG artefacts around edges |
| Images with transparency | PNG | JPG cannot store transparency |
| Archival copies | PNG | Identical pixels, smaller than uncompressed TIFF |
| Photos for email or the web | JPG | Much smaller files |
TIFF (Tagged Image File Format) dates back to 1986 and is now maintained by Adobe. It is a container that can hold images in many different ways: uncompressed or compressed (LZW, Deflate/ZIP, PackBits, CCITT fax compression and others), in black and white, greyscale, RGB or CMYK, at 8 or 16 bits per channel, with or without transparency, and with any number of pages in one file.
That flexibility is why scanners, document-management systems, fax servers, archives and print workflows rely on it. It is also why it is so poorly supported elsewhere: handling every TIFF variant is complicated, so browsers and many apps simply don't.
PNG is lossless, like an uncompressed TIFF, but it is universally supported by browsers, operating systems, office suites and websites. Converting TIFF to PNG therefore changes the format without changing the picture: every pixel of your scan is stored exactly.
That matters for documents. JPG compression creates faint smudges around the edges of text and lines, which makes scans look fuzzy and can hurt OCR accuracy. PNG keeps text crisp, line art clean and fine detail intact. For photographs you only want to share, JPG is smaller; the tool lets you switch between the two.
Scanners and fax systems often save a whole document as one multi-page TIFF. PNG holds one image per file, so the converter writes one PNG per page and numbers them in order: invoice_page_1.png, invoice_page_2.png and so on. Download them individually or as one ZIP.
To turn the pages back into a single document that is easy to share, combine the PNGs with the Image to PDF converter. To search or copy the text, run the pages through Image to Text (OCR).
Transparency in a TIFF is kept in the PNG. High bit-depth TIFFs (16 bits per channel, common in professional scanning and photography) are converted to 8 bits per channel, which is what screens display; keep the original TIFF if you need the extra precision for editing.
CMYK TIFFs, typical of print work, are converted to RGB because PNG has no CMYK mode. The conversion is not colour-managed, so saturated colours may shift a little. For print-critical work use colour-managed software; for viewing, sharing and documentation the PNG is perfectly suitable.
Scanned documents are often sensitive: contracts, IDs, invoices, medical and legal paperwork. Here they never leave your device. The converter uses libtiff, the standard open-source TIFF library, compiled to run inside your browser, and the PNGs are saved straight to your downloads folder.
Large scans need memory while they are processed, roughly four bytes per pixel. An A4 page scanned at 600 dpi is about 35 megapixels, so convert very large multi-page files on a desktop computer for the smoothest experience.
Many scanners default to TIFF because it is lossless and supports multiple pages. If you scan often and always end up converting, check your scanner software for a PNG or PDF option: PNG for single pages you will edit or publish, PDF for multi-page documents you will send. For archival scanning, where institutions often require TIFF, keep scanning to TIFF and convert copies here whenever you need to share or view them.
A resolution of 300 dpi is the usual standard for documents, 600 dpi for small print, fine line art or photos you may enlarge, and 150–200 dpi is enough for on-screen reading.
Lossless files of high-resolution scans can still be large. If the PNGs are for on-screen viewing or an upload with a size limit, reduce the resolution with the Image Resizer (150–200 dpi is plenty for reading on screen), or switch to JPG output for photographic pages.
View and share scans in any browser or app with text kept perfectly sharp.
Split multi-page TIFFs from fax servers and archives into numbered PNGs.
Browsers can't show TIFF; PNG displays everywhere without quality loss.
Keep transparent backgrounds from TIFF artwork when moving it to other tools.
Yes for standard 8-bit images. PNG uses lossless compression, so every pixel of the decoded TIFF is stored exactly. Images with 16 bits per channel are reduced to 8 bits per channel, which looks the same on screen but has less editing headroom.
Each page becomes its own PNG, named with the page number (for example scan_page_1.png, scan_page_2.png). Download them all together as a ZIP.
Yes. If the TIFF has an alpha channel, the PNG keeps it. Converting to JPG would fill transparent areas with white instead.
PNG keeps every pixel, which matters for scanned text, line drawings, logos and anything you will edit again. JPG is smaller and better for photos you only want to view or share; switch the output format to JPG for those.
The converter uses libtiff, the standard TIFF library, compiled for the browser. It reads the common TIFF variants: uncompressed, LZW, Deflate (ZIP), PackBits and JPEG-compressed files, in colour or greyscale, single or multi-page. If a file uses an unusual variant, the tool says it cannot create a preview instead of producing a broken image.
CMYK images are converted to RGB because PNG has no CMYK mode. The conversion is not colour-managed, so colours can shift slightly; use colour-managed software for print-critical files.
Usually, if the TIFF was uncompressed: PNG compresses losslessly, so scans of documents shrink dramatically. A TIFF that was already compressed with LZW or ZIP may be about the same size as the PNG.
No. Decoding and PNG encoding both run in your browser, which suits confidential scans such as contracts, invoices and medical documents.
