Crop TIFF

How to Crop TIFF Images Online

1. Choose Your TIFF Files: Drag and drop TIFF images onto the page or click "Choose TIFF files" — up to 50 at once. The first photo opens in the editor and the rest line up as thumbnails below it; with two or more photos open, "Add more" adds files to the same batch.
2. Set the Crop: In Crop, pick an "Aspect ratio" ("Free", "Original", 1:1, 4:3, 16:9 and more) or a platform size, then drag the box on the photo or type its width and height under "Crop area". "Shape" switches between "Rectangle" and "Circle (avatar)". The crop applies to every photo in the batch.
3. Pick the Output Format (Optional): "Save as" keeps "Same as original" or saves as JPG, PNG, WebP or another format. For JPG, WebP and AVIF output, the "Quality" slider (40–100) trades file size against detail. Resize, Crop, Rotate and Flip all work in the same session, and "Undo" steps back.
4. Download: Click the Download button, which names the output format (for example "Download PNG"), for one photo, or "Download all (.zip)" for a batch — "Download one by one" saves the files separately. The editor opens TIFF files right in your browser whenever your browser can decode them, so those files are not uploaded. A file it can't decode is either processed on our servers and deleted automatically afterward — the editor says so before you download — or skipped with a note. No sign-up, no watermark.

Why Crop TIFF Images?

TIFF (Tagged Image File Format, Adobe TIFF 6.0 specification, 1992) is the workhorse format for prepress, scanning, archival imaging, and scientific capture. Unlike JPG or HEIC, a TIFF crop can be genuinely lossless: this editor re-saves it with lossless Deflate (ZIP) compression, so for an 8-bit RGB, greyscale or black-and-white scan the kept pixels are bit-identical to the source. That makes cropping a low-risk edit even on irreplaceable masters, and explains why TIFF stays standard for the workflows below.

• Trim scanner borders from document and book scans — flatbed scanners and book cradles leave black bezels, platen edges, and gutter shadows around the page; cropping to the document area produces clean inputs for OCR (Tesseract, ABBYY) and reduces archive storage proportionally to the area removed.
• Match prepress trim, bleed, and safe-zone marks — commercial print specs are pixel-exact. A 300 DPI letter-size CMYK TIFF for offset print needs the bleed area trimmed to the precise trim line before plate output; note that this editor saves a CMYK TIFF as RGB and does not keep the ICC profile, so do press-ready CMYK trims in a prepress tool and use this page for proofs and RGB deliverables.
• Standardize medical and microscopy frames — DICOM workflows often export grayscale TIFF for slide review, telepathology, and AI training datasets; cropping every frame to the same field of view keeps measurement scales comparable and shrinks the training corpus.
• Reduce GIS and remote-sensing raster size — GeoTIFF aerial and satellite tiles can run hundreds of megabytes per scene; cropping to the area of interest before downstream analysis (QGIS, ArcGIS, GDAL) cuts memory pressure and avoids paging (the saved crop does not keep GeoTIFF georeferencing tags).
• Crop multi-page fax and document TIFFs — fax-style multi-page TIFFs (CCITT G4) stack many bilevel pages in one file; split them into pages first, then cropping removes header bars and edge artifacts from each page (this editor crops and saves the first page of a multi-page file).
• Extract a region for high-resolution print — pulling a tight crop from a 50–100 MP scanning-back capture lets a small subject fill a poster-sized print without resampling.

If your source is JPG or PNG, use the format-specific cropper — Crop JPG, Crop PNG, or the general Crop Image — and export as TIFF in one step. For a different edit on the same file, Resize TIFF, Rotate TIFF, Flip TIFF, and Compress TIFF keep the TIFF container. To bundle the cropped pages into a single document, Merge TIFF to PDF or Convert TIFF to PDF is the next step.

TIFF Compression on Crop — What Each Option Does

The crop itself is lossless on the pixels you keep. This editor has no compression-type setting — it always writes lossless Deflate — so the table explains the schemes you may meet in source files and in other tools; if the output must use a specific one, run it through Compress TIFF.

In tools that let you choose, keep LZW or uncompressed for colour print masters and scientific imaging. For bilevel document archives, CCITT G4 stays the densest option. Avoid JPEG-in-TIFF if the file may be cropped or edited again later — every JPEG re-encode adds generational loss.

Aspect Ratios — Common TIFF Use Cases

The "Aspect ratio" chips (1:1, 3:2, 4:3, 16:9 and more) hold a fixed ratio while you drag the crop box; for the ratios below that have no chip (5:4, 7:5, 7:9, US Letter, A4), pick Free and type the pixel size under "Crop area".

Frequently Asked Questions

Is cropping a TIFF actually lossless?

Yes for a standard 8-bit RGB, greyscale or black-and-white TIFF. The saved TIFF is always lossless Deflate (there is no compression choice, so no lossy JPEG-in-TIFF either). Cropping discards the pixels outside the rectangle, but the kept pixels are bit-identical to the source — no re-quantization, no re-sampling. The exceptions are noted when the file opens: a 16-bit TIFF is saved as 8-bit, a CMYK TIFF as RGB, and a wide-gamut profile (Adobe RGB, ProPhoto) is converted to sRGB.

How are multi-page TIFFs cropped?

The editor works on the first page of a multi-page TIFF. Downloaded without an edit, the file is your original with every page; once you crop it, the saved TIFF holds the first page only, and the editor says so as soon as the file opens ("This TIFF has N pages: an edit here keeps only the first page"). For fax-style document scans, book scans, and CCITT G4 archives where every page needs the same crop, split the multipage TIFF into single-page files first, crop each, and re-merge with Merge TIFF to PDF for a single-document output or keep them as individual TIFFs.

Does the cropper preserve the source compression, ICC profile, and DPI?

Only the DPI: the XResolution/YResolution tags are kept. The compression is always lossless Deflate whatever the source used (there is no compression dropdown), the ICC profile is not kept (Adobe RGB and ProPhoto are converted to sRGB, CMYK to RGB), and 16-bit samples become 8-bit. Black-and-white (1-bit) and greyscale scans stay 1-bit and greyscale.

Can I crop a 16-bit or 32-bit TIFF without losing precision?

No. The editor works in 8 bits per channel: a 16-bit TIFF is saved as 8-bit, with a note when the file opens, and there is no bit-depth setting. High-bit-depth precision is one of the main reasons photographers, scientific imagers, and prepress operators choose TIFF over JPG, so for that work crop in a tool that keeps 16 or 32 bits (Photoshop, GIMP, ImageMagick, libvips) and keep the original.

Will OCR still work on a cropped document TIFF?

Yes, and it usually works better. Tesseract, ABBYY FineReader, and most commercial OCR engines benefit from clean inputs without scanner bezels, page-edge shadows, or stray fingertips. Crop to the actual document area of a scan made at 300 DPI minimum (600 DPI for small text); the saved TIFF keeps the DPI tag, is lossless (a black-and-white scan stays 1-bit), and the OCR pass on the cropped file is faster and more accurate than on the raw scan.

Why is the cropped TIFF still so large?

TIFF stays large because it is lossless by design — even LZW or Deflate compression on a high-resolution photographic image often only shaves 20–40% off the uncompressed size. This editor saves TIFF as lossless Deflate with 8 bits per channel, so a 4000×3000 RGB photo cropped to half the area still comes out at several megabytes or more, not "small". If file size matters more than fidelity, pick JPG under "Save as", or use Compress TIFF, Convert TIFF to JPG or Convert TIFF to PDF for much smaller outputs for sharing.

Can I crop multiple TIFF files to the same rectangle at once?

Yes — drop up to 50 TIFF files at once (a mixed batch works too). The crop region (or aspect-ratio preset) you set applies to every file in the batch; "Download all (.zip)" saves every cropped result in one ZIP, or use "Download one by one" to save them separately.

Does the cropper change my CMYK separations or alpha channel?

Yes for CMYK: a CMYK TIFF is saved as RGB, with a note when the file opens, and its colour profile is not kept. TIFFs with an alpha channel (e.g., from Photoshop) keep transparency in the saved RGBA TIFF. Only the flattened image is saved, so extra masks, spot colour channels and layers in the TIFF are not carried over.

Should I use .tif or .tiff for the output?

The two extensions name the same format — .tif is the original 8.3-filename DOS extension, .tiff is the four-letter form Apple and most modern software now prefer. The bytes are identical. When the output stays TIFF, the editor keeps your file's own spelling (a .tif stays .tif, a .tiff stays .tiff), so if a downstream pipeline expects .tif specifically (some prepress RIPs and older imaging libraries do), start from a .tif or rename the result; Crop TIF works the same way.
