よくある質問
Quick answers.
›Are my images uploaded to your server?
No. All image processing occurs locally in your browser session using the Canvas API; your files are never transmitted or stored externally.
›Which image formats are supported?
The editor supports standard web formats including JPEG, PNG, WebP, and GIF. Output is typically saved as a PNG or JPEG depending on your preference.
›Can I undo my changes?
Yes. The editor maintains a local state that allows you to revert filters or text overlays before you finalise the export.
›Will the image quality decrease after editing?
Cropping and adding text preserve the original pixels, though saving as a JPEG may introduce slight compression artifacts. For the highest quality, we recommend exporting as a PNG.
