Compress image for website
Make the image lighter without making it useless.
Set the limit your website needs. File. Set. Go. searches for a useful result within that requirement and can reduce oversized dimensions before sacrificing practical quality.
Prepared in your browser. Your supported image stays on your device while it is processed.
Deterministic fixture
The target is a requirement, not a quality preset.
A fixed quality slider cannot know the upload limit. File. Set. Go. tests bounded options and returns a result under the target only when the actual encoded file fits.
Smaller still has to be useful.
The result is not judged by byte count alone. The same image remains inspectable after a 93.9% reduction in file weight, while the engine stays within its governed quality and dimension limits.
Illustrative fixture result. Difficult images and different targets produce different outcomes.
Dimensions and file weight solve different parts of the problem.
A giant image can be heavy because it carries far more pixels than its website placement can display. Reducing that excess can protect visible quality better than pushing compression harder.
- Preserve dimensions
- Use a hard boundary when the exact pixel size must remain.
- Allow reduction
- Let the bounded search step down dimensions when the target cannot otherwise be reached.
- Unreachable target
- Get an honest outcome instead of a file that quietly exceeds the limit.

Enter the website limit
Set the KB or MB target, optional maximum dimensions and whether reduction is allowed.

Use the verified result
Download the file when the actual encoded output meets the governed requirement.
Your image itself is not uploaded for processing.
Supported preparation runs in your browser. HEIC workflows may load File. Set. Go.'s same-origin decoder resources.
Common questions
Will File. Set. Go. always reach my target size?
No. Some targets are too small for the selected dimensions and governed quality range. File. Set. Go. reports an unreachable outcome instead of pretending the file fits.
Why might the dimensions become smaller?
When dimension reduction is allowed, a smaller pixel boundary can meet a difficult file-size target while preserving more useful visual quality than extreme compression.
Does compression have zero quality loss?
No. Lossy JPEG and WebP preparation can change image detail. The workflow searches within governed quality limits and keeps the result practical rather than promising lossless output.
What if my image is already small?
An already-small file may not shrink dramatically, and converting it again may not improve it. Use a requirement that matches the image's real website job.
Is my image uploaded to a processing server?
No. Supported image preparation happens in your browser. HEIC may load the same-origin decoder resources needed for that format.
Make the file fit the website requirement, not a guess.
Bring the limit you have. File. Set. Go. will search within its quality and dimension guardrails and tell you when the target is not practical.
