POPULAR FILE-SIZE LIMITS
Start with the limit your upload form asks for.
Each guide opens the same private compressor with the target already set, then explains the quality, format, and dimension choices that matter for that limit.

Compression that starts with your outcome.
Most tools choose a compression level and leave you to check the result. TargetKB starts with the rule you need to pass.
Keep what matters
TargetKB searches for the highest quality that fits, and only resizes when it has to.

THE CLEAR ANSWERS
Before you drop a file.
Are my images uploaded?
No. Compression happens inside your browser. Your image bytes are never sent to TargetKB servers.
Can every image reach any target size?
Not without trade-offs. If a target is extremely small, TargetKB will warn you before reducing dimensions or producing visibly lower quality.
What is included for free?
Single-image compression, target KB or MB, upload-ready verification, visual comparison, and download are free without an account.
What does Pro add?
Pro is built for repeat work: batches, whole folders, reusable presets, ZIP downloads, and a clear processing report.
