Frequently Asked Questions
Are my photos uploaded to an external server?
No. All image scaling, canvas rendering, and format conversions execute strictly inside your local web browser memory. Your images never touch an external server.
Will resizing a PNG preserve transparency?
Yes. When exporting to PNG or WebP, full alpha channel transparency is preserved without adding white backgrounds.
What is Nearest Neighbor interpolation?
Nearest Neighbor scaling prevents blur by duplicating exact pixel colors, making it essential for scaling retro pixel art, 3D sprite sheets, and voxel textures.
What is the maximum resolution supported?
Because the tool utilizes your local hardware GPU and Canvas memory, you can scale images up to 8K and 16K resolutions depending on your browser memory limits.
