PicWish Image Upscaler vs SupaRes

PicWish Image Upscaler is an AI service for enlarging images, offered by a Hong Kong maker founded in 2021. It accepts PNG, JPG, JPEG, JFIF, WEBP, and BMP files. The service supports batch processing, API access, and a desktop app, and its maximum enlargement scale is custom rather than a fixed listed value. The free plan costs nothing and allows limited non-HD downloads each day. A Pro plan provides daily HD downloads for most online features, but no price is listed. Pay-as-you-go credits also have no listed price and remain permanently valid after purchase. A monthly subscription supplies a budget of API credits; unused subscription credits can roll over while the subscription remains active. PicWish lists API as a platform while also providing online and desktop workflows for image enlargement. The available facts describe scaling and access options, but not a fixed maximum size or prices for paid plans.

SupaRes is an AI image enhancement platform that upscales, restores, denoises, fixes, and optimizes images. Its listed tools include super-resolution, face enhancement, tone adjustments, artifact reduction, low-light boost, and noise removal. An image optimization engine is intended to balance file size with visual quality. The browser-based image manager includes cloud storage and team collaboration, and API access supports processing through HTTP requests. The API accepts direct uploads or public image URLs, supports webhooks, and documents external storage such as AWS S3. API calls require an API key and HTTPS, with HTTP Basic Auth or Bearer Auth available. Temporary processed-image URLs are deleted after one hour; the documentation says external storage URLs can point to permanent storage. SupaRes sets one credit per processed image, even when multiple available enhancements are applied. The Free plan is free and includes a one-time quota of 10 credits, a 64-megapixel limit, and one user. Paid monthly plans start at $9.00 per month for Basic, with 100 credits and a 128-megapixel limit. SupaRes is based in Berlin, Germany, and has no desktop app.
