Reduce Image Size
Hit Any Upload Limit
Type a target size - 150 KB, 2 MB, anything - and the tool iteratively searches encoder quality and dimensions until your image fits underneath it.
How targeting works
- You setTarget KB/MB
- Engine triesQuality first

How to reduce an image to a target size
- 01Upload the imageAny JPG, PNG, or WebP up to 30 MB.
- 02Enter your limitWhatever the form, portal, or email system demands - in KB or MB.
- 03Download the fitted fileThe engine reports the final size, dimensions, and whether the target was met exactly.
Features
Binary-search quality
Instead of guessing, the engine probes multiple quality levels and keeps the highest one under budget.
Dimension fallback
If quality alone can't reach very small targets, it scales dimensions progressively until the file fits.
Honest best-effort mode
When a target is physically unreachable, you get the smallest reliable result plus a clear explanation.
Format choice
JPG for photos, WebP for efficiency, PNG when the format is mandated.
Single-file focus
Tuned for getting one important image exactly right rather than bulk throughput.
No sign-up gates
Open the page, drop the file, done.
Limits people commonly need to hit
Why iterative targeting beats manual guessing
No trial-and-error loop
Manually re-exporting at lower quality five times is what this automates.
Maximum quality under the cap
Because the search keeps the highest passing quality, you never overshoot downward.
Clear outcomes
You always know whether the target was reached or the result is a best effort.
Works on any image
Photos, scans, signatures, certificates - the algorithm adapts to content.
What 'compress to 200 KB' actually requires
File size targets are constraints, and satisfying a constraint optimally means searching. The engine encodes your image at several quality levels, measures each output, and narrows the bracket until it finds the highest quality whose file fits. That's why results keep more detail than the naive approach of dropping quality until something passes.
Some targets are impossible at full resolution. A 4000×3000 photo squeezed into 30 KB will always look rough no matter the encoder settings, so the second stage scales dimensions down in measured steps. Each step re-runs the quality search at the new size, because a smaller image needs less quality reduction to fit.
The honest part matters: when even minimum quality at reduced dimensions can't reach the target, the tool says so instead of quietly handing you a mangled file. Knowing the floor lets you make a real decision - accept slightly larger output, crop the image, or start from a cleaner source.
“The visa portal wanted exactly under 300 KB. One attempt here beat twenty minutes of screenshotting my own photo.”

“Candidates constantly send 6 MB scans; I normalize everything to 500 KB before filing.”

“Our LMS rejects files over 1 MB. This is the only tool that reliably lands under the line without wrecking worksheets.”

Frequently asked questions
How exact is the target size?
The engine aims to land under your target, as close to it as possible. Upload systems care about staying beneath the limit, not hitting it precisely.
What if my target is impossible?
You'll receive the smallest reliable result along with a clear message explaining the constraint, so you can adjust the target or the source image.
Which format reaches small sizes best?
JPG and WebP both compress aggressively. PNG only fits small targets after significant dimension reduction.
Will the image be resized?
Only if needed. The search prefers keeping original dimensions and scales down only when quality reduction alone cannot reach the target.
Is there a minimum target?
Targets down to roughly 10 KB work for small images. Extremely small targets on huge photos will trigger the honest best-effort path.
Does the tool upload my image?
No. Every encode attempt happens in your browser's memory.
