Understanding your file size limit
The 150 KB limit is a maximum, not an exact byte count. PixNimble searches for the highest JPEG or WebP quality that fits, then reduces dimensions if needed. Check the final dimensions if your upload form also specifies a minimum width or height. Here, 1 KB is 1,024 bytes and 1 MB is 1,048,576 bytes.
Supported formats
Upload JPG, PNG or WebP images. Export JPG, PNG or WebP. HEIC uses a local decoder when needed; AVIF depends on browser support. Maximum input: 40 MB and 32 megapixels. Animated files export as a single still image.
A few helpful answers
Will the file be exactly 150 KB?
No. The tool aims for 150 KB or less (153,600 bytes). It reports the measured output size and only marks the target met when the file fits.
Will a 150 KB target change my dimensions?
Possibly. The compressor lowers quality first for JPG and WebP. If that is not enough, it reduces dimensions. PNG is lossless, so its dimensions may need to shrink sooner.
