ProofGrid Contact Sheets

ProofGrid turns a photo selection into an organized contact sheet, with captions, page previews and files you can actually save.

SELECT AND ARRANGE
Import JPEG, PNG or WebP photos through the Android system picker. Include or omit individual images, rotate their presentation, add captions and move photos earlier or later. The Check view flags images whose short edge is below 1,200 pixels so you can review source detail.

LAY OUT THE SHEET
Choose A4 or US Letter, 2–4 columns and 3–6 rows. Preview each page before delivery. Show or hide file names and captions. Images fit inside their cells; the complete caption stays in the CSV index.

SAVE A REAL HANDOFF
Create a multipage PDF, one high-resolution JPEG per page and a CSV image index. Preview files inside the app, then save them through Android Files or share them to an app you choose. Delivery files represent the saved job revision; create a new delivery after edits.

KEEP AN EDITABLE BACKUP
Export a source ZIP containing the job, original photo bytes and working images. Restore a valid ProofGrid Android ZIP as an independent job. Save backups outside the app before uninstalling or clearing storage.

BUILT FOR LOCAL WORK
One purchase. No ads, account, subscription, analytics or cloud upload. Phone and landscape tablet layouts. An optional generated example set lets you try the workflow; a new library starts empty.

FORMATS AND LIMITS
JPEG, PNG and WebP only, up to 20 MiB and 50 megapixels per image. Up to 60 photos per job, 20 jobs and 512 MiB of private photo/output storage. Original bytes are retained; working images are normalized to JPEG with a maximum 4,000-pixel long edge. Transparent images use a white background. Page JPEG dimensions use 300 pixels per inch of the PDF page geometry. This is a selection and contact-sheet tool, not a color-managed print proofing service or photo editor.

Android source ZIP backups are not interchangeable with iOS job JSON files. Source backups retain original photo metadata. Sharing and saving files are your explicit actions; the chosen destination may have its own data practices.
