Pick a 2x or 4x factor per photo. A 1,000px original becomes a clean 2,000 or 4,000 pixel file.
Outputs can reach 8,192px on a side, enough for print, zoom crops and marketplace zoom tools.
Crystal reconstructs edges, texture and type rather than interpolating, so enlarged photos stay sharp.
The same command handles video with the Crystal video upscaler, billed per megapixel-second.
Billing follows the upscaled megapixels, about 4 credits per MP with a 25 credit minimum. A typical 2x photo lands at 25.
The enlarged file arrives as a normal chat attachment: preview it, rerun at a higher factor, or download.
Drop the image into the chat with /upscale. JPEGs, PNGs and web photos all work.
Choose the enlargement factor. 2x doubles each side; 4x quadruples it, up to the 8,192px ceiling.
The upscaler synthesizes edges and texture at the new resolution instead of stretching pixels.
The result arrives in the chat at about 4 credits per output megapixel, 25 credits minimum.
Bring supplier photos up to the resolution a storefront zoom expects.
Sharpen scanned prints, thumbnails and saved-from-the-web images.
Push a file to the pixel dimensions a poster or large print needs.
Meet the minimum image sizes Etsy, Amazon and Shopify require.
Rescue video stills and low-res assets for covers and headers.
A 4x upscale rebuilds edges and texture convincingly, but a face blurred to 20 pixels stays unrecognizable. Start with the best source you have.
Billing follows output megapixels, so a 4x enlargement to 8,192px costs more than the 25 credit minimum. The estimate shows before it runs.
There is no free plan for upscaling. Pro starts at $20 per month. For a single image, the free upscaler tool is enough.
Not fully. /upscale runs on credits from 25 credits per image, scaled by output size. Pro is $20 per month and includes monthly credits. A free single-image version lives on the tools page.
2x or 4x per run, up to 8,192 pixels on a side. A 512px photo can come back at 2,048px, and larger sources can reach print resolution.
Yes. The same /upscale command processes video with the Crystal video upscaler, billed per megapixel-second instead of a flat image rate.
About 4 credits per output megapixel with a 25 credit minimum. A typical 2x photo to a few megapixels costs 25 credits; a max-size 8,192px output costs more.
