Troubleshooting and FAQ
Questions
Are my images uploaded?
No. Every operation runs inside your browser. The extension has no server, no account and no analytics, and stores nothing but your theme choice. The only network request it makes is fetching an image you chose with Open in DL Image Tools, from that image's own address.
Does it keep EXIF data?
No. Compressing, resizing, converting, cropping, rotating and flipping all remove EXIF data, so camera details and GPS locations are not passed on. The Metadata tab can tell you whether the original had any.
Can I edit SVG files?
No. DL Image Tools works with pixel images: JPG, PNG, WebP, AVIF, GIF and BMP.
Can I keep a GIF animated?
No. GIF images can be imported but are saved as a still JPG or another format you choose.
Where are my downloads?
In your browser's normal download folder, unless your browser asks where to save each file.
Is it on the Chrome Web Store or Firefox Add-ons?
It has been submitted to both. Until a listing is live, install it from the GitHub release. See Install.
Troubleshooting
"That file type isn't supported. Try JPG, PNG, WebP, AVIF, GIF or BMP."
Cause: The file is not one of the supported image types, for example an SVG, HEIC or TIFF.
Fix: Convert it to JPG or PNG with another program first. When several files are dropped, only the unsupported ones are skipped.
"Couldn't load that image (the site may block cross-origin access)."
Cause: Open in DL Image Tools fetches the image again, and the website does not allow that.
Fix: Use Download image from the same menu, then import the downloaded file.
AVIF shows "(not supported)" or is greyed out
Cause: Your browser cannot create AVIF files.
Fix: Use WebP, which gives similar savings, or update your browser.
The popup closed and my image is gone
Cause: Browser popups close when you click outside them, and their content is not kept.
Fix: Download results before you leave the popup. For longer work, right-click an image on a page and choose Open in DL Image Tools, which opens the tools in a tab that stays open.
The extension disappeared from Firefox
Cause: It was loaded as a temporary add-on, which Firefox removes when it closes.
Fix: Load it again from about:debugging, as described in Install.
Saved shows 0%
Cause: The image is already well compressed at the chosen quality and format.
Fix: Lower the quality, choose WebP, or resize the image.
