Open Tool →What Is TIFF and Why Does It Matter?
TIFF (Tagged Image File Format) was developed in the 1980s and has become the gold standard for lossless image storage in professional workflows. Unlike formats designed for web delivery, TIFF prioritizes pixel fidelity above everything else. Every pixel is stored exactly as captured — no palette limits, no lossy compression, no generational quality loss when you save and re-save. This makes TIFF the format of choice for print production, photo archiving, scanning workflows, and any situation where the image will be edited, color-corrected, or printed at high resolution.
TIFF supports full-color 24-bit RGB imagery, optional alpha channels, 16-bit per channel for HDR work, and multiple compression modes (uncompressed, LZW, ZIP, JPEG). The uncompressed variant produced by this tool opens in every application that supports TIFF without any codec requirement — from Adobe Photoshop to GIMP to Windows Photo Viewer to professional RIP (raster image processing) software used in commercial printing.
PNG and TIFF: Both Lossless, Different Use Cases
PNG (Portable Network Graphics) is the dominant lossless format for web and screen use. It uses deflate compression to reduce file size while preserving every pixel, supports full alpha transparency, and is natively supported in every web browser. PNG excels at screenshots, UI assets, logos, and any image that needs to be lossless on the web.
TIFF occupies a different niche: professional print production, scanning, and archiving. While PNG is designed for screen delivery, TIFF is designed for maximum compatibility with print and post-production software. Many commercial printing workflows, RIP software systems, and document management platforms require TIFF as their input format and may not accept PNG at all. Even when PNG is technically accepted, TIFF is often preferred because it is the established industry standard with decades of software support.
Converting PNG to TIFF does not improve or degrade image quality — both are lossless. What it does is repackage the same pixel data in a container format that is more broadly accepted in professional print and archival environments.
When Should You Crop and Convert PNG to TIFF?
- Delivering to a print production workflow. If your designer or printer requires TIFF and your source asset is a PNG logo, photograph, or graphic, this tool converts it in seconds — with the option to crop out only the relevant content area.
- Extracting a region from a PNG layout or screenshot. If you have a large PNG — a full-page screenshot, a mockup, or a UI export — and you need only a specific region as TIFF, the crop tool lets you isolate that element without opening a full image editor.
- Archiving PNG assets in a TIFF-based document system. If you are migrating an image library to TIFF for long-term preservation or compatibility with an archival system, this tool handles the PNG-to-TIFF conversion step without requiring Photoshop or a command-line tool.
- Preparing images for color correction software. Some professional color correction tools prefer TIFF as input because it is a more universally supported container for raw pixel data. Converting your PNG to TIFF first ensures compatibility.
- Removing unnecessary whitespace or padding from a PNG. The crop handles let you trim the canvas to the actual content area before converting, saving file size and simplifying downstream layout work.
PNG vs TIFF: Format Comparison
| Property | PNG | TIFF |
|---|---|---|
| Compression type | Lossless deflate | Uncompressed or lossless LZW/ZIP |
| Color depth | 8 or 16-bit per channel | 24-bit RGB, 32-bit RGBA, 48-bit HDR |
| Transparency | Full 8-bit alpha channel | Full 8-bit alpha channel |
| File size (photo) | Moderate — deflate compresses well | Large — every pixel stored fully |
| Print production support | Acceptable | Industry standard |
| Animation support | APNG (limited browser support) | No (static frames only) |
| Editing without quality loss | Yes — lossless | Yes — no generational loss |
| Best for | Web graphics, UI assets, lossless web images | Print, archiving, post-production |
How the Crop Workflow Works in the Browser
The PNG to TIFF Crop Converter loads your file using URL.createObjectURL and decodes it via img.decode(). This approach resolves only when the image is fully decoded and ready to paint — ensuring the canvas always receives real pixel data. The decoded image is drawn onto an HTML5 Canvas, and an SVG overlay renders the crop rectangle and handles on top.
When you drag a handle, the tool maps canvas coordinates back to the original image's pixel dimensions using a scale factor (natural width ÷ display width). This ensures the crop is applied at full resolution — the canvas is only a display proxy. When you click Convert & Download TIFF, an off-screen canvas draws only the selected region using drawImage with source rectangle parameters. The tool reads the raw RGBA pixel data with getImageData and manually encodes a valid TIFF binary: a little-endian IFD header with 11 standard tags followed by uncompressed RGB pixel strips. The result is a valid, universally compatible TIFF file with no external library required.
What the TIFF Encoder Produces
The encoder produces a baseline TIFF (Revision 6.0 compatible) with the following characteristics: little-endian byte order, uncompressed pixel storage (Compression tag = 1), RGB photometric interpretation (tag = 2), 8 bits per sample per channel, 3 samples per pixel, resolution set to 72 DPI. This profile is the broadest possible TIFF subset — it opens without issue in Photoshop, GIMP, Affinity Photo, Preview, Windows imaging tools, and RIP software. The file does not use JPEG compression or any proprietary extension.

Does cropping a PNG before saving as TIFF affect quality?
No quality is lost in the conversion step. Both PNG and TIFF are lossless formats. Cropping selects a region and discards the rest. The TIFF encoder stores the decoded pixel data from that region without any further compression or quality reduction. The output TIFF is a lossless representation of exactly the pixels you selected.
How large will the output TIFF be compared to the PNG?
Uncompressed TIFF stores 3 bytes per pixel (RGB). A 500×500 crop produces a TIFF of approximately 750 KB of pixel data plus a small header. A comparable PNG might be 50–300 KB depending on image content. The TIFF will almost always be significantly larger — this is expected and reflects the uncompressed lossless storage. If file size is a concern after converting, open the TIFF in an image editor and re-save with LZW compression, which can reduce TIFF file size by 30–70% for photographic content.
Can I use the output TIFF in Adobe Photoshop?
Yes. The output TIFF is a standard baseline TIFF that opens directly in Photoshop, GIMP, Affinity Photo, and any other professional imaging application. No special import settings are required.
Is the conversion really free with no file size limit?
Yes. Because processing runs entirely in your browser, there is no server to impose a limit. The only practical limit is your device's available RAM. There are no usage caps, no watermarks, and no account required.
