Image compressor
Upload a PNG, JPEG, or WebP image and your browser exports a JPEG at the original pixel dimensions using the selected quality; transparent pixels become white, with a file-size comparison.
How to use this tool
Upload a PNG, JPEG, or WebP image and choose the JPEG quality. The browser re-encodes it at the original pixel dimensions and compares the actual input and output file sizes.
Re-encode an image as JPEG in your browser and inspect the actual output size before using it.
💡 3 Quick Steps to Get Started
Choose PNG, JPEG or WebP with the file picker; there is no dropzone.
Adjust quality from 0.35 to 0.95, default 0.72, and wait for encoding.
Check preview, size and dimensions, then download -compressed.jpg.
When it helps
Use it to try reducing a photo or web image as a JPEG without changing its pixel width or height.
How it works
Browser canvas fills transparent areas with white, then exports a JPEG at the selected quality from 35% to 95%. The original pixel dimensions are preserved.
Worked example
Upload a 2 MB WebP image, set quality to 72%, compare the source and JPEG sizes, and download the result.
Limits and data handling
JPEG size depends on the image content, source format, and selected quality, so re-encoding can produce the same size or a larger file. Empty, unsupported, oversized, or over-limit images and browser encoding failures produce no download. There is no separate cancel button after processing starts; choosing another file or quality ignores the old result.
The image and quality setting stay in your browser. Image content is not sent to the GoGo Tools backend or stored by the site.

Workflow and limits
Choose PNG, JPEG or WebP with the file picker; there is no dropzone.
Adjust quality from 0.35 to 0.95, default 0.72, and wait for encoding.
Check preview, size and dimensions, then download -compressed.jpg.
Decoded dimensions are retained and transparency is filled white. JPEG is lossy; neither size reduction nor visual fidelity is guaranteed, and output can be larger than the source.
Image contents are processed in the browser without upload. Check actual size against the receiving form limit.

FAQ
Image compressor: Which images can I upload, and what can I adjust?
Upload PNG, JPEG, or WebP files up to 20 MB and 32 million pixels. JPEG quality can be set from 35% to 95%.
Image compressor: What changes in the downloaded image?
Browser canvas re-encodes the image as JPEG at the original pixel width and height and reports the actual source and output sizes. Transparent pixels become white, and original EXIF or other metadata is not copied.
Image compressor: Why might the result not be smaller?
JPEG size depends on the image content, source format, and selected quality, so re-encoding can produce the same size or a larger file. Empty, unsupported, oversized, or over-limit images and browser encoding failures produce no download. There is no separate cancel button after processing starts; choosing another file or quality ignores the old result.
Image compressor: Is my image uploaded or stored?
The image and quality setting stay in your browser. Image content is not sent to the GoGo Tools backend or stored by the site.
