FAQ

Click to expand FAQs and technical specifications

Q1.Are my uploaded photos stored on remote servers?
No. All image stitching, preview drawing, and high-resolution compiles occur entirely inside your browser memory. Zero files travel to servers, ensuring 100% local privacy protection.
Q2.What is the difference between scale and padded modes?
Scale mode scales photos to match identical width or height, eliminating ragged gaps. Padded mode keeps 100% original dimensions without scaling, filling gaps with background colors.
Q3.How does the gradient color background work?
We pre-configured modern colorful linear-gradient presets. Simply click one of the gradient balls in the sidebar to add dynamic, aesthetic borders to your photo collage instantly.
Q4.Does the stitched image lose quality?
No. You can customize the export settings to select lossless PNG (which preserves every single pixel), or high-res JPG/WEBP. The final composite matches the original coordinates at a 1:1 scale.
Q5.Will my browser freeze if stitching dozens of huge images?
To prevent client-side out-of-memory crashes, our editor workspace displays debounced low-res previews. High-resolution canvas rendering is executed offscreen only at the moment you click download.
