Full Steps
Choose a Gemini image
For a Gemini image, save the original file first and upload a JPEG, PNG or WebP up to 15 MiB and 20 MP. For an initial test, try up to one image a day for free, subject to availability; an account balance allows batches of up to 20 images.
Give processing time to finish
Processing starts automatically after upload and keeps the Gemini image at its original dimensions. With the upload complete, you can close this tab and return in the same browser to follow progress; keep your original for a detailed comparison later.
Review your Gemini result
Look at the Gemini result beside the original at full size to review text, faces and small textures. Save the finished file within its one-hour download period; if a quality warning is shown, read it and review the affected details before using the image.

Frequently Asked Questions
Will deleting metadata remove Gemini's SynthID?
A Gemini SynthID watermark is in the pixels, so a metadata-only cleanup is not enough. Image processing also clears the file's embedded metadata; use the separate checker to review supported provenance signals if needed.
Why does one Gemini image take longer than another?
Initial startup and a busy queue affect the wait, while text-heavy images can need more time. Follow each image's status until the result is ready to download.
