Enlarge an image by 2× or 4× using smooth interpolation. This guide explains the practical workflow, what to check in the output and when another tool is a better fit.
When to use this tool
Choose the supported 2× or 4× enlargement and create a smoothly interpolated result within the output limits.
A practical example
Enlarge a 400 × 300 image by 2× to produce an 800 × 600 copy.
Check the exported result
Compare edge smoothness at full resolution and check the actual dimensions.
Common problems and limits
This operation interpolates pixels; it does not reconstruct missing details or provide generative AI restoration.
Choose the next step
Sharpen Image can adjust edge appearance after resizing, with moderation.
Files, privacy and saving
This tool offers browser processing for the supported operation. Check the selected processing mode before continuing; server options require an explicit upload choice. Keep your original, review the downloaded result and choose a clear filename before sharing it. The privacy policy explains the processing approach.
