How do I put two photos side by side with no gap in between?

Upload your two photos, select the 2-Cell Horizontal (Side-by-Side) layout template, and drag both the Gutter Spacing slider and the Corner Radius slider all the way down to 0px. The two images will touch seamlessly down the center.

Why does changing the layout template not stretch or distort my photos?

Each cell uses proportional center-cover scaling (similar to CSS object-fit: cover). Instead of squashing a vertical photo to fit a horizontal cell, it scales the photo proportionally and lets you drag inside the cell to adjust the framing.

What resolution is the downloaded collage image?

The master export canvas renders at high resolution (typically 2000px to 3000px on the longest edge depending on your chosen aspect ratio preset), keeping fine text and photography crisp on Retina displays.

Can I swap the positions of two photos after loading them into the grid?

Yes. You can reorder or swap cells directly inside the workspace or click any individual cell to replace just that slot with a different image from your device.

Which export format should I choose: PNG, JPG, or WebP?

Choose PNG if your collage contains UI screenshots with small text or sharp graphics. Choose JPG (90% quality) for photographic collages you plan to print or post on social media, or WebP for the smallest file size on websites.

Are my photos uploaded to a server when I create a collage?

Never. Every photo stays inside your local browser memory and is composited onto a local HTML5 canvas element.

Free Photo Collage Maker Online - Custom Grids

When you need to place two screenshots side by side for a before-and-after comparison, group four product angles into a single e-commerce square, or build a moodboard without signing up for a bloated cloud design suite, open this photo collage maker in your browser. Pick from responsive 2-to-9-cell grid templates, pan and zoom each photo inside its cell, adjust gutter spacing, corner radius, and background color, and export a high-resolution PNG, JPG, or WebP locally.

Everyday layouts where a clean photo grid beats sending separate files

Sending four separate attachments in a chat message or email forces the reader to open each image one by one and flip back and forth to spot the difference. Combining them into a single structured frame tells the story in one glance:

Side-by-Side Before & After comparisons (2-Cell Split): Designers comparing UI v1 versus UI v2, photographers showing raw versus color-graded edits, and contractors documenting a repair job rely on a clean 2-column horizontal or vertical split.
Marketplace multi-angle squares (3-Cell & 4-Cell Grids): Online marketplaces and social feeds reward a 1:1 square image showing the front view in a large main cell on the left and two or three close-up detail shots stacked on the right.
Documentation & step-by-step mobile screens: Putting three tall smartphone screenshots side by side inside a 16:9 landscape frame lets you embed an entire three-step mobile onboarding flow as a single crisp figure in a blog post or README.

How to use the photo collage maker step by step

Drop 2 to 9 photos (JPG, PNG, WebP) into the workspace, or click any individual cell in the canvas to assign a photo to that slot.
Select a Grid Layout Template (such as 2-Up Side-by-Side, 2-Up Stacked, 1+2 Hero Split, 2×2 Quad Grid, 3×2 Six-Grid, or 3×3 Nine-Grid) and an Output Aspect Ratio (1:1 Square, 4:5 Portrait, 16:9 Landscape, 4:3, or 9:16 Story).
Adjust the Border / Gutter Spacing (0px for seamless edge-to-edge up to 48px), Cell Corner Radius (0px square corners to 32px rounded cards), and Canvas Background Color (White, Black, Slate, or custom HEX).
Drag inside any cell to pan or zoom the photo framing, swap two cells if needed, and click Export High-Res Image (PNG, JPG, or WebP).

Cell-level framing, aspect ratio presets, and spacing controls

A good grid builder handles photos of mismatched orientations (such as mixing a vertical phone photo with a horizontal desktop screenshot) without stretching or distorting either image.

Object-cover smart cell fitting with pan & zoom: Every cell automatically scales its assigned photo to cover the cell frame proportionally without aspect-ratio distortion, while letting you pan and zoom inside each cell to center faces or product details.
Asymmetric & Symmetric Grid Templates: Switch instantaneously between classic symmetric matrices (2×1, 1×2, 2×2, 3×2, 3×3) and editorial hero layouts (1 Large Left + 2 Stacked Right, 1 Large Top + 3 Bottom).
Precision Gutter, Outer Padding, and Corner Radius sliders: Set 0px spacing when stitching a seamless side-by-side comparison, or dial in 16px spacing with 12px rounded corners on a soft slate background for a modern bento-grid presentation.
High-resolution canvas rendering (up to 2048px–3000px): Unlike mobile apps that compress collages down to blurry 720px JPEGs, the exporter renders the master canvas at crisp print and Retina screen resolution.

Worked example: assembling a 4-angle product bento grid at 2048×2048 px

Suppose you are listing a mechanical keyboard on an online store and have four photos of different sizes:

Hero-Angle.jpg (4000 × 2667 px landscape)
Keycap-Macro.jpg (3024 × 4032 px portrait)
Side-Profile.jpg (3800 × 2400 px landscape)
USB-Port-Detail.jpg (3000 × 3000 px square)

To combine all four into a single 2048 × 2048 px (1:1) catalog square:

You drop all four photos into the collage maker and choose the 1 Top Hero + 3 Bottom Detail layout (or the 2×2 Quad Grid) at a 1:1 Square aspect ratio.
You set Gutter Spacing = 16 px, Corner Radius = 14 px, and Background Color = #F8FAFC (clean off-white studio gray).
Inside the macro cell, you zoom in slightly to center the keycap legends.
You select WebP (90% Quality) and click Download. The resulting collage-2048x2048.webp weighs 410 KB and presents all four angles in a single, balanced frame.

Tips for seamless side-by-side comparisons and print exports

When building a Before & After technical comparison (for example, showing an uncalibrated image on the left and a color-corrected image on the right), set both Gutter Spacing and Corner Radius to 0 px (or set Gutter to a thin 2 px white divider line). Matching the canvas aspect ratio to the combined width of your two source images ensures neither side is cropped.

If you plan to combine multiple full-page document scans into a multi-page file rather than placing them on a single single-sheet grid, use the Image to PDF tool instead so each image gets its own dedicated page in a PDF binder.

100% local in-browser canvas rendering

Your personal family photos, unreleased product shots, and UI screenshots never leave your computer or phone. All grid layout math and high-resolution canvas rendering run locally inside your browser tab.

Choosing aspect ratios and export resolutions for print vs social feeds

Before dragging photos into cells, picking the right outer canvas ratio prevents awkward social-feed cropping later:

Square (1:1, 2048 × 2048 px): Ideal for Instagram grid posts, product marketplace comparison tiles, and digital album covers.
Portrait Story (9:16, 1080 × 1920 px) & Feed (4:5, 1600 × 2000 px): Maximizes vertical screen space on mobile feeds, Reels covers, and Pinterest pins.
Widescreen Landscape (16:9, 1920 × 1080 px): Built for YouTube thumbnails, blog hero headers, desktop wallpapers, and presentation slides.
Print-grade A4 / 4×6 layouts: When printing a framed collage at 300 DPI, keep gutter spacing between 12 px and 24 px with a clean white (#FFFFFF) canvas border so physical picture frames do not cover the outer edges of your subjects.
