Before splitting, decide the row and column order and whether the destination expects gaps, overlap or print bleed. A simple exact-pixel split supplies none of those production assumptions unless you deliberately add them elsewhere. ## Define the job before editing A tile export divides one pixel grid into separate files. Before splitting, decide the row and column order and whether the destination expects gaps, overlap or print bleed. A simple exact-pixel split supplies none of those production assumptions unless you deliberately add them elsewhere. ## Check boundaries and reconstruction Use numbered row-and-column filenames and retain the full image as the reference. Open tiles from the corners and center, then reconstruct a small preview in the intended order. Uneven dimensions are normal when the original size cannot be divided exactly by the grid. ## Make the decision from evidence A set of image tiles does not ensure that a social platform, web gallery or printer will lay them out correctly. Check the destination’s current behavior and use its templates when applicable. Never discard pixels simply to make all tile dimensions match unless the crop is intentional. ## A worked planning example Example: A width of 1001 pixels split into three columns produces widths of 334, 333 and 334 pixels with rounded boundaries. The total remains 1001, so the outer edge has not silently disappeared. ## A practical checklist 1. Choose the grid and destination assumptions. 2. Export with row-and-column names. 3. Reconstruct a preview to verify order. 4. Keep the uncut source alongside the tiles. ## Keep a traceable result Keep the source file, the working copy and the delivery copy as separate items. Record the input and the changes you actually made so another person can understand the result later. These workflow examples are planning examples, not documented customer outcomes or proof of a successful restoration. ## FAQs Are exact image tiles ready for tiled poster printing? They may need additional overlap or bleed. Follow the printer’s requirements rather than assuming a pixel split is a complete print layout. Should I replace my original with the edited copy? Keep the source unchanged and save a separate working or sharing copy. An export, edit or AI interpretation can omit information that remains useful in the source. ## Sources Preservation and technical guidance reviewed for this article. - MDN Web Docs: [Pixel manipulation with Canvas]() ## Related - [Open the related free tool]() - [Join Photos into a Strip Without Calling It a Panorama]() - [Check Frame Orientation Before Cropping a Photo]() - [Browse photo guides]() - [Free image tools]() ## Ready to restore your photos?
