Trusted by teams resizing at catalog scale
Ecommerce, agencies and platforms run high-volume resize jobs on Picnie - in the dashboard or via API.
“We drag in product shots, pick Amazon and Instagram sizes, then export one ZIP. Season launches are much faster.”
“Our agency runs five brands through multi size presets - Instagram, Meta and email sizes export in a single ZIP.”
“The Resize Image API plus webhooks replaced our cron + ImageMagick scripts. Batches notify Slack when done.”
One preset. Every channel covered.
Pick a marketplace or social size once - apply it to the entire batch. Or define custom width, height and fit per job.
