How do I calculate pixel dimensions for a print job with bleed?

Multiply your bleed document dimensions in inches by your output DPI. For a US Letter document (8.5"×11") with 0.125" bleed on all sides, the bleed dimensions are 8.75"×11.25". At 300 DPI: 8.75×300 = 2625 pixels wide, 11.25×300 = 3375 pixels tall.

Does the tool resample or resize images, or only crop?

Crop only. Deliteful extracts a sub-region of the image without scaling or resampling. Output pixel density is determined entirely by the source image.

Can I use this to trim images submitted with incorrect dimensions by photographers?

Yes. If a photographer delivers an image that's oversized relative to your trim spec, use explicit box crop coordinates to extract exactly the region you need for your document layout.

What file formats are supported for print production use?

PNG, JPEG, and WebP are supported as both input and output. For print work, JPEG and PNG are most common. The original format is preserved on output — no format conversion is applied during the crop.

Crop Images to Print Trim and Bleed Dimensions Before Prepress

Print production workflows fail at the imagesetter when supplied images don't match the trim box dimensions — a 3300×2550 image submitted for a 3375×2625 bleed print job will be rejected or manually padded by the printer at your expense. Deliteful's image crop tool lets you extract an exact pixel region to match your document's trim or bleed spec before handoff.

At 300 DPI, a US Letter document with 0.125" bleed on all sides requires an image of 2625×3375 pixels. If your photographer delivered a 4000×5000 image, an explicit box crop with the right coordinates extracts that exact region — keeping the subject in frame while hitting the dimensional spec. The centered crop mode works for bleed-safe crops where the subject is centered and bleed is added symmetrically.

The tool preserves the original format and does not apply scaling or resampling — crop only. For print work, this means you control resolution by choosing a source image with sufficient pixel density, then extract the correct region. A 300 DPI crop from a 600 DPI source still delivers 300 DPI output at the target dimensions.

How it works

1
Calculate target pixel dimensions
Convert your trim or bleed dimensions from inches to pixels at your output DPI (e.g., 8.75" × 11.25" at 300 DPI = 2625×3375 px).
2
Set crop parameters
Use centered crop for symmetrically-framed images, or explicit box coordinates to extract the region that aligns with the trim and bleed area.
3
Upload, crop, and verify
Download the cropped file and verify pixel dimensions in your image viewer or preflight tool before submitting to the printer.
