FILEFIX GUIDE
Compress an image to a target size
When a website or form gives you a maximum file size, the goal is not simply “make it smaller.” You need a file that stays within the limit while remaining clear enough to use.
KB and MB limits
A file-size requirement such as “maximum 100 KB” is a hard ceiling. Your final file should be below the stated limit, because rounding or platform differences can occasionally matter.
Choose the right format
JPEG is usually practical for photographs because it provides strong compression. PNG is useful when you need lossless graphics or transparency, but a photographic PNG can be much larger.
Leave a little headroom
If a portal says 100 KB maximum, aiming for roughly 90–95 KB gives you a small safety margin. FileFix lets you specify a maximum size and processes supported images locally.
Keep privacy in mind
For personal documents, local processing can be useful because the original image does not need to be uploaded to a server.
