Compress Image
Re-encode a JPG, PNG or WebP image with an adjustable quality setting and download a copy in the same format.
Open Compress ImageStep-by-step instructions
- Choose one JPG, PNG or WebP image that fits the current upload limits.
- Adjust the Quality slider. Start with the default setting, then lower it if a smaller JPG or WebP is more important than fine detail.
- Run Compress Image and save the downloaded file.
- Compare the result with your original at full size and check both file sizes before deciding which copy to use.
Supported files and result
The input is one JPG/JPEG, PNG or WebP file. The result keeps that file format and its pixel dimensions, allowing for automatic correction of supported JPEG rotation metadata.
This tool changes encoding rather than image dimensions. Use Resize Image when you also need fewer pixels, or Convert Image to change the file type.
Choosing quality
The Quality control runs from 40 to 95. For JPG and WebP, lower settings generally reduce file size at the cost of detail. Look closely at small text, faces, gradients and sharp edges.
PNG uses lossless compression. Its setting changes compression effort rather than applying the same visual-quality tradeoff as JPG. A PNG can stay similar in size or become larger after re-encoding.
Limits and troubleshooting
A smaller result is not guaranteed, especially when the original is already optimized. The tool does not target an exact file size in KB or MB.
If dimensions or memory are too large, make a smaller source copy and try again. File size alone does not describe how much memory an image needs. Invalid or unsupported images should be re-saved as a supported static format.
Processing and privacy
The selected files are uploaded to Helphonic for processing in private storage. No third-party file-processing service is used. Temporary source and output files are removed after the download response, and failed processing cleans up temporary files. Keep your originals and save the result to your device.
Access and current limits
Check the tool page for current access, remaining usage and per-operation limits. File count, per-file size, total size and page limits can depend on your access and can change. Device and processor safety limits still apply when usage is unlimited. A paid pass does not necessarily increase every processing limit.
One successful export counts as one operation, including its multiple files or pages. Changing options and local previews do not use an operation. Current access checks must complete before the tool can release the result.
Check the current limits
Allowances and per-operation limits can change. The Compress Image page shows the policy that applies to you. Per-operation safety limits still apply when usage is unlimited. See access passes if a tool or extra usage requires paid access.
