FAQ
Will image quality be preserved?
Quality is optimized automatically, and you can manually adjust quality and dimensions for better results.
Can I batch resize images to 150KB?
Yes for Pro accounts. Batch mode supports up to 10 files at once.
Common situations for this workflow
Application systems with strict image-size caps.
Portals that reject uploads when the format or dimensions are off.
Repeat workflows where you want a faster path from upload to acceptance.
Checklist before you upload
Start with resize image to 150kb as the main requirement, then adjust dimensions only if the target is still too large.
Use JPEG or WebP first when a portal rejects larger files or strict PNG exports fail to compress enough.
Test the final file before submission so you can confirm the upload system accepts the size, format, and dimensions.
Tips to hit the target faster
The original photo may be much larger than the upload limit, so compression alone is not always enough.
Many systems require both file size and pixel dimensions, not just one of them.
Lossless formats like PNG often stay too heavy for strict upload caps compared with JPEG or WebP.
