GridFlow: Photo Collage Maker

GridFlow: Photo Collage Maker is a focused photo collage maker and image utility
for Android. Create photo collages, build photo grids, combine photos, stitch
screenshots into long images, resize pictures, convert JPG, PNG and WebP files,
add watermarks, compare images, and pick colors from photos.

workspace. It is built for everyday image jobs: arranging pictures, joining
screenshots, preparing files for upload, marking images with a watermark,
reviewing visual changes, and exporting clean results.

Photo collage maker and photo grids
Create neat picture collages from multiple images. Make photo grids for family
photos, travel memories, product pictures, study notes, portfolios, design
references, and social posts.

Image stitching and long screenshots
Stitch screenshots or photos vertically or horizontally into one long image.
Combine chats, receipts, tutorials, web captures, process notes, visual guides,
and before-and-after layouts.

Image stacking
Stack photos side by side or top to bottom. Create comparison strips, progress
photos, mood boards, product sets, thumbnails, and clean presentation layouts.

Image splitting
Split one photo into multiple parts for grid layouts, previews, post sections,
creative crops, and organized image exports.

Watermarking
Add text or image watermarks before sharing, publishing, uploading, or sending
photos. Mark ownership, prepare branded visuals, and keep image exports clear.

Resize and convert
Resize pictures for upload forms, product listings, documents, profile images,
storage, printing, and sharing. Convert image files when you need JPG, PNG,
WebP, or another supported format.

Format conversion
Change image formats from a simple workflow. Prepare photos and screenshots for
apps, websites, documents, messages, design tools, and file compatibility needs.

Image compare
Compare two images to review edits, exported versions, screenshots, designs,
mockups, and before-and-after changes.

Color picker from image
Pick colors directly from photos for design palettes, brand references, UI work,
thumbnails, artwork, and creative projects.

GridFlow is useful for creators, students, online sellers, designers, reviewers,
and anyone who regularly prepares images on Android. Whether you are making a
photo collage, joining screenshots, resizing product photos, converting image
files, adding a watermark, comparing versions, or sampling colors, GridFlow
keeps the workflow direct and focused.
