Combine multiple photos into a single grid layout, or split one photo into an Instagram-ready tile set — free, right in your browser, no signup and no upload to a server.
How It Works
The Image Grid Generator runs entirely on your device using your browser’s built-in Canvas engine, so your photos are never uploaded anywhere.
Photo Grid Collage mode takes the images you add and arranges them into a grid you control: pick a preset like 2×2 or 3×3, or set a custom rows × columns layout, then adjust spacing, corner rounding, background color, and output shape (square, 4:5 portrait, or 16:9 landscape). Each photo is automatically cropped to fill its cell without stretching, using the same cover-fit logic browsers use for CSS background-size: cover. The finished grid downloads as a single PNG or JPG image.
Instagram Grid Splitter mode works the opposite way: it takes one photo and slices it into equal tiles — a classic 3×3 grid, a wide 3×1 banner, or a tall 1×3 banner — so that when you post the tiles in order, they reassemble into one seamless image across your profile grid. Each tile downloads individually or as a single zip file.
Use Cases
- Social media content creators use the collage mode to build multi-photo carousel covers or Instagram feed previews, and the splitter mode to plan a 3×3 “puzzle” grid on their profile.
- Freelancers and agencies use the collage mode to quickly assemble before/after client work, portfolio thumbnails, or product comparison grids for a proposal or case study — without opening a design tool.
- Site owners and bloggers use it to create a single combined image for a blog post or product listing image instead of embedding several separate photos.
Frequently Asked Questions
How do I make a photo grid from multiple pictures?
Upload your photos in Photo Grid Collage mode, choose a grid template (like 2×2 or 3×3), and the tool arranges them automatically — reorder photos with the up/down controls, then download the result as a PNG or JPG.
How do I make an Instagram grid?
Switch to Instagram Grid Splitter mode, upload one photo, and choose a 3×3 layout — the tool slices it into nine tiles sized for Instagram, which you then post left-to-right, top-to-bottom so they line up into one image on your profile.
What size should Instagram grid tiles be?
1080×1080 pixels per tile is the standard size Instagram displays at full quality; the tool also offers 1350×1350 for extra detail and 720×720 for smaller files.
Can I control the spacing between photos in a grid?
Yes — the spacing slider in Photo Grid Collage mode adjusts the gap between every photo in the grid, from no gap at all up to a wide 40px border.
Does this image grid generator work on a picture with the wrong aspect ratio?
Yes — every photo is automatically cropped to fill its grid cell using a center-crop, so mismatched photo shapes and sizes don’t create gaps or distortion.
Is this grid generator free, and do I need to sign up?
Yes, it’s completely free with no signup, no watermark, and no image ever leaves your browser — everything is generated locally using canvas rendering.
What file formats can I upload and download?
You can upload JPG, PNG, or WebP photos, and download your finished collage as a PNG (for transparency and sharp edges) or JPG (for smaller file size).
