Compress image
Compress images locally and control the final file size
Use compression when an image must load faster, fit an upload limit or travel through email and catalog systems without becoming unnecessarily heavy. QuokkaPix lets you tune quality, format and target size locally, then inspect the result before using it.

What this tool does
Reduce image file size locally with quality, target size and format controls.
Quality slider and target-size workflow.
JPG, PNG, WebP, AVIF and advanced encoder paths when available.
Single-file and batch compression.
Useful for websites, stores, email and documentation.
How it works
1
Load one image or a batch.
2
Choose output format and quality or target size.
3
Preview visual detail around text, edges and gradients.
4
Export and compare final file size with the destination limit.
Compression checks before export
Compression is successful when the file reaches the target size without creating artifacts that matter for the destination.
| Check | Why it matters | What to do |
|---|---|---|
| Target file size | Email, CMS and marketplace limits are usually byte limits, not preview-quality limits. | Compare the downloaded file size with the actual upload requirement. |
| Artifact review | Low quality settings can damage gradients, faces, labels and product edges. | Inspect flat colors, small text and shadows after export. |
| Quality floor | Repeated lossy compression can degrade the same image over multiple edits. | Keep the original and compress from the best available source. |
| Format choice | WebP or AVIF may beat JPG for delivery, but not every destination accepts them. | Choose the smallest format that the target system actually supports. |
FAQ
Are images uploaded for compression?
No. Compression runs locally in the browser.
Why does a lower quality value not always make a tiny file?
Source content, dimensions, format and transparency all affect the final size.
Can I compress many files at once?
Yes. Batch mode applies the same compression settings and returns a ZIP.
