Image Quality Issue When Generating Stickers Using PhotoRoom Legacy Template API

API Troubleshooting
, ,
1

I am currently using the Image Editing API v1 – Legacy endpoint to generate stickers using a template:

https://image-api.photoroom.com/v1/render?apiKey=${process.env.PHOTOROOM_API_KEY}&templateId=${templateId}&imageUrl=${imageUrl}

The issue I’m facing is that the output sticker quality is noticeably lower than the original uploaded image—appearing pixelated and blurry.

Since the documentation for the legacy API is no longer available, I haven’t found any information about parameters for controlling:

  • Output resolution
  • DPI
  • Render size
  • Quality settings
  • Higher-quality border generation

I need the generated sticker to match the original image quality, or at least have a way to specify higher resolution or quality during render.

Questions:

  • Is there any query parameter (e.g., width, height, quality, scale, upscale, HD mode, etc.) still supported in the legacy /v1/render endpoint?
  • If not, is there an equivalent method in a newer API version that allows generating stickers using a template without losing quality?
  • Does the legacy template rendering pipeline downscale images by default?

Any guidance or updated documentation would be very helpful.

Hi there,

Could you perhaps share an example of what you’d like to see as an output example?

Thanks in advance

Please find below the images attached where the original is the one with the background.
Kindly provide a solution asap as it is delaying the launch of our project.
Thanks

Hi @waleedsajid575, could you share why you are still using V1 for the Image Editing API?

For example, we do have the HD background removal model, and this is our documentation for V2 of the image editing API.

Basically it removes the backround and creates a sticker with white border around the image and i can add the background as well. In my case i was told by your team to use the legacy api to get the border around the image along with the background removal.
