About This Tool
Compress Image re-encodes browser-decodable pictures with an adjustable quality setting and selected JPG, WebP, or PNG output. It reports the actual size change instead of promising that every result will be smaller.
What You Can Do
Quality control
Choose a 10–100 percent encoder quality or a preset.
Output choice
Export JPG, WebP, or PNG.
Batch processing
Multiple inputs are returned in a ZIP archive.
How to Use

Practical Use Cases
Website uploads
Reduce photographic assets to meet practical upload limits.
Email preparation
Create smaller copies for attachments while retaining originals.
Privacy and File Processing
Compress Image keeps its JPG, JPEG, PNG, or WEBP input in browser memory while the operation runs. The workflow creates JPG, PNG, WEBP, or ZIP for batches for local preview or download and does not send the entered values or selected file bytes to the GXA Toolbox application server.
Supported Inputs and Outputs

Output

- ZIP for batches
Quality and Fidelity
JPG and WebP quality settings are lossy. PNG export uses the browser PNG encoder and ignores JPEG-style quality; changing format can also change transparency and file size.
Limitations and Important Notes
- A compressed result can be larger when the source is already optimized or the target format is less efficient.
- JPG output removes transparency.
- Repeated lossy encoding progressively degrades image detail.
Worked Example
Use a representative source image, apply Compress Image, and compare the result with the original at full size before publishing it.
Helpful Tips
- Keep the untouched source image while evaluating Compress Image.
- Check the JPG or PNG or WEBP or ZIP for batches result at its intended display size.
Frequently Asked Questions
Does Compress Image overwrite the selected image?
No. Compress Image creates a result or extracted value without overwriting the selected source.
What affects Compress Image results?
JPG and WebP quality settings are lossy. PNG export uses the browser PNG encoder and ignores JPEG-style quality; changing format can also change transparency and file size.
Can a very large image fail in Compress Image?
Yes. Compress Image remains subject to browser decoding, canvas, model, and memory limits.
