Questions

How much does image upscaling cost?
Each image costs 5 credits at either size. New accounts receive 50 credits, enough for 10 images. A $5 pack covers 100 images; the $8 monthly plan adds enough credits for 200 images if you spend them all here.
Which images can I upload?
Upload a still JPG, PNG or WebP up to 10 MB and 1,048,576 pixels, for example 1024 by 1024. Larger originals must be resized first. Downloads are WebP images; transparent backgrounds are preserved.
Does AI upscaling recover every original detail?
No. Upscaling estimates detail from the source image. Small text, faces and intricate patterns can change. Compare the result with your original before publishing or printing it.
What happens if one image in my batch fails?
Each image is processed and charged separately. Failed jobs receive an automatic credit refund. Successful images remain available to download individually or together in a ZIP.
Are my photos stored?
Uploads go to private storage and are deleted after processing. Fal processes the image; we disable request-payload retention and request deletion of its generated files after one hour. Results stay in your browser until you leave the page, so download them before closing it.
