Alternative FAQ
Choose with clear limits.
Is ImageBig a direct replacement for Bigjpg?
Not for every use. ImageBig focuses on free private browser previews up to 2048 pixels, while Bigjpg publicly positions itself around larger enhancement workflows, mobile and desktop apps, and an API. Confirm current provider limits before choosing.
Which option keeps the source image on my device?
ImageBig's free preview processes the image in the browser. Desktop tools can also process locally. Server-based online tools require uploading files, so review their current privacy terms.
Should I choose ImageBig for a 24-megapixel print?
No. The free ImageBig preview is capped at 2048 pixels on the longest edge. Use a dedicated print pipeline for production-scale output.
