How Image Collage & Contact Sheet Maker works
Build a photo collage around the images you actually want to show. Use a balanced grid for equal emphasis, a featured photo on the left or at the top for a visual focal point, or a horizontal filmstrip for a short sequence. The last grid row expands to fill the available width instead of leaving empty cells. All photos remain individually selectable in the preview.
Start with the destination: square for a compact board, portrait for a taller composition, story for a vertical panel, landscape for a wide presentation, or A4 proportions for a printed sheet. A layout is a starting point rather than a fixed template. Adjust spacing, outer margins, corner rounding and background colors, then check faces, products and text before downloading.
Exports reproduce your arrangement and crop choices without the selection outline. Choose PNG for lossless output, or JPEG and WebP with a quality setting to trade file size against compression artifacts. PDF places a raster copy on one A4 page with print margins. Export dimensions are pixels, not a guarantee of print sharpness: source photos are resized to a 1600-pixel longest edge to keep browser memory manageable.
How to use Image Collage & Contact Sheet Maker
1. Add and arrange your photos
Add up to 16 photos or drop files into the editor. Move the strongest image to the first position for a featured layout.
2. Choose the composition
Select a layout and canvas shape. Adjust grid columns, spacing, margins, corners and color theme while checking the preview.
3. Refine individual photos
Select each tile to adjust crop position, zoom, rotation and flip. Edit captions and enable them only when useful.
4. Export and inspect
Choose the output size and image format, or download a one-page A4 PDF. Open the exported file to check sharpness and captions before sharing or printing.

Collage ideas you can build in the editor
Choose equal-sized grids for comparison or a featured layout for emphasis. Keep the most important parts of each image inside its crop.
A four-photo travel story
Choose the square grid with two columns. Four images get equal emphasis; switch to featured-left when one portrait should lead. Use the crop sliders to keep faces inside the frame.
A twelve-photo contact sheet
Choose A4 proportions and three grid columns. Turn on captions, shorten labels to meaningful shot names, and use whole-image fit at 1× zoom when reviewers need to see each complete frame. Download the A4 PDF for a one-page proof.
A product detail board
Place the main product image first in a featured layout and use remaining tiles for details. Use a consistent background and verify that cropping has not hidden a label or product edge.

Frequently asked questions
How many photos can I add?
The editor keeps up to 16 photos, with a 20 MB and 60-megapixel limit per file. Choose browser-decodable image files. Unsupported or oversized files are skipped with a message. Images are resized to at most 1600 pixels on their longest edge for editing, so very large exports may upscale them.
Can I change the crop of just one photo?
Yes. Click the photo in the preview, then adjust its zoom and horizontal or vertical crop position. Rotate it in 90-degree steps or flip it horizontally. Choose Show whole image to fit the complete photo at 1× zoom; higher zoom can crop it again. Reset crop restores the initial position, zoom and orientation.
Can I reorder or remove photos?
Drag the photo-order cards or use their earlier/later arrow buttons, which also work on touch devices and with a keyboard. Select a photo and choose Remove photo to remove only that image. The first photo becomes the large image in featured layouts.
Which canvas shapes and export formats are supported?
Choose square, 4:5 portrait, 9:16 story, 16:9 landscape or A4 proportions. Image exports use a 1200, 2400 or 4096-pixel longest edge. PNG, JPEG and browser-supported WebP are available. The PDF export fits the collage onto one A4 page with margins; it contains a raster image, not editable vector artwork or multiple pages.
Are captions editable and are my photos uploaded?
Captions start with the filename without its extension. Edit each caption and enable Show captions to include it in the export; long captions are shortened to fit their cell. Photos are decoded and composed on your device, without uploads to an image-processing server. This editor does not save projects: download your work before refreshing or closing the page.
