Read the Privacy Policy →Choose a practical image quality
JPEG and WebP compression works by re-encoding the image. Start with a moderate quality setting, compare the preview with the original, and reduce quality only when the visual result remains acceptable.
For websites, compress a copy and keep the original source file. Screenshots with sharp text may need a higher quality setting than photographs.
Choose settings for photos and screenshots
Compression works best when the settings match the image. Photographs tolerate different choices than screenshots, diagrams, and images containing small text.
Why image size changes
JPEG and WebP store visual information with adjustable quality. Lower quality can remove fine detail and reduce bytes; reducing pixel dimensions can produce a larger saving when an image is wider or taller than its intended display size.
A practical starting point
For a web photograph, begin near 80 quality and compare the preview at normal viewing size. For screenshots or interface captures, keep quality higher so text and sharp edges remain readable. Always retain the original file.
Questions about this tool
Will compression change the image dimensions?
Quality compression alone keeps the current pixel dimensions. Dimensions change only when resize controls are used.
Why is a PNG sometimes not much smaller?
PNG is designed for lossless graphics. Photographs usually compress more efficiently as JPEG or WebP, while PNG remains useful for transparency and sharp flat-color artwork.
Compress images without losing the details that matter
Balance file size against visible quality before downloading a new copy.
How to use it
- Choose a JPEG or WebP image.
- Adjust quality while checking the preview.
- Download the compressed copy and retain the original.
Supported input
- JPEG photographs and screenshots
- WebP images supported by the browser
Worked example
Compress a 4.8 MB product photograph at quality 80, then compare its text and edges before saving the smaller copy.
Limitations
- Lossy compression can soften fine detail.
- The tool does not repair damaged images.
Troubleshooting
- If text looks soft, increase quality.
- If savings are small, resize oversized dimensions first.
Tool-specific questions
Does it overwrite my image?
No. A new downloadable file is created.
Why is the result still large?
High dimensions and detailed scenes require more data even after compression.
Before you process
Can I use this image compressor online without uploading my input?
Yes. This tool is labelled On-device, so the selected input is processed in your browser and is not sent to a ForgeMyFile processing API.
What happens if the browser cannot process it?
The tool shows a readable error and stops. It does not silently fall back to a cloud upload.
Why can performance differ between devices?
The browser is doing the work locally, so speed and practical file size depend on available memory, CPU and browser capabilities.
