Screenshot Stitcher

Join images vertically or horizontally, then save one PNG or JPEG. Set the order, how widths or heights match, spacing and background, and crop the edges of each image by hand.

Images to join

0 of 10 images

Up to 10 images. 20 MB per file, 80 MB total, and 16M pixels per image.

Images are processed on this device. Files and settings are not saved or sent automatically. Saving starts only when you choose Save image.

Screenshot Stitcher

Choose 1–10 still PNG or JPEG images, arrange their order, and join them vertically or horizontally. Match the width or height to the largest image, the first image, or the smallest image, or keep each image at its original size. Crop the top and bottom edges for a vertical join, or the left and right edges for a horizontal join. Set the gap, outer padding, and background color, then save as PNG or JPEG. PNG can have a transparent background; JPEG quality is adjustable.

Limits and formats

  • Still PNG and JPEG only. Animated images such as APNG are not supported.
  • Each image is limited to 20 MiB and 16 megapixels. The selection is limited to 10 images, 80 MiB total, and 48 megapixels total.
  • Output is limited to 16 megapixels and 16,000 px on either side. Gap and padding can each be 0–256 px.
  • If a PNG cannot be confirmed as still from its first 2 MiB of header data, it is rejected for safety. Re-save PNGs with unusually large leading metadata and try again.

Notes

Images are processed in your browser; files and settings are not saved automatically. Canvas re-encoding removes metadata such as capture time and location. Browser and device canvas memory and export limits vary, so an output may fail even within the stated limits. Automatic overlap detection, OCR, and scrolling capture are not available.

This tool processes your input and files on this device (in your browser) and does not send them to a server. See Privacy and ads for details.

  • Image resizer

    Convert JPEG, PNG and WebP images one at a time or in batches. Resize, adjust JPEG/WebP file size, and save successful results as a ZIP.

  • Make a solid background transparent

    Turn a white or single-color background transparent and save logos, signatures and line art as transparent PNGs. Choose the color, tolerance and area, and check what will be removed before saving.

  • Straighten a document photo

    Line up the four corners of a document photographed at an angle and get a straight, rectangular image. Shadows on the paper can be whitened. Save as JPG or PNG.

  • HEIC to JPG converter

    Convert HEIC (HEIF) photos from an iPhone or other devices to JPG on this device and save them. The orientation stays as you see it, and location and other camera data are not included in the JPG.
