Existing local editing

  • Images stay on your device

    Processing never uploads your images automatically or switches to the cloud after a failure.

  • Cancel when you need to

    Cancel the current batch and choose another set of images when ready.

  • Export completed results

    Test credits do not limit existing free exports.

How to use it

  1. Create an API key (1 free credit on signup)

    Sign in to your account page to mint a rac_live_... API key. Only its SHA-256 hash is stored server-side, with revocable access.

  2. Call POST /v1.0/removebg

    Drop-in compatible with remove.bg v1.0 parameters (image_file, image_url, size, format, channels, type, roi, bg_color, crop, shadow_type).

  3. Atomic FEFO holds & safe retries

    Pass Idempotency-Key for safe retries with zero double-charging; upstream errors release credit holds automatically.

Requirements and limits

Cloud L4 GPU workers process images strictly in volatile RAM and never persist input or output image bytes.

Frequently asked questions

Which images can I use?

Use JPG, PNG or WebP, up to 20 MiB per image. The main editor keeps up to 4 image items; use the separate batch page to process multiple files. Use images you own or have permission to edit, and check the results.

Are my images uploaded to a server?

On-device mode processes images in your browser. A local processing failure does not switch to a server. Server processing is not enabled. First use needs model and runtime downloads; offline use is not guaranteed.

Why can’t I import an image URL?

Only public HTTP(S) image URLs are supported. Your browser requests the image directly without cookies; the source sees the request. The source must allow cross-origin access, and the image must meet size and format limits. If CORS blocks it, download the image and upload it instead. We do not bypass restrictions with a server proxy.

How do I cancel a job or refine an edge?

Cancel while processing, then choose another image when ready. On the result screen, choose a solid or image background, use the edge editor to erase or restore areas, undo changes, and check your export. Cancelling never starts a cloud job.

Which formats can I download?

Export individual results as PNG, JPG or WebP. PNG and WebP can preserve transparency. Completed batch results can be downloaded as a ZIP. Allow your browser to save the file; the page does not bypass system download prompts.

Are the test account and credits real?

Registration, verification, password recovery, credits and checkout in this preview use browser-local test data. Only @example.test addresses are accepted; the test inbox does not send email. Test credits do not represent a payment or real balance and do not sync across devices. Clearing site data removes these test records.
