Reduce Image File Size
Compress and resize images right in your browser.
A free browser-based tool for compressing and resizing JPG, PNG, and WebP images. It supports dimensions, percentage scaling, quality controls, output-format selection, and target file-size compression.
The user problem
People who need to compress an image or generate a QR code usually need it done once, quickly, and without creating an account. Existing options are often cluttered with ads, force uploads to unknown servers, or bury the core action behind sign-ups and upsells.
Reduce Image File Size was built around the opposite approach: open the page, do the job, leave. No account, no queue, no upload to a server when the browser can do the work locally.
What the tool does
A free browser-based tool for compressing and resizing JPG, PNG, and WebP images. It supports dimensions, percentage scaling, quality controls, output-format selection, and target file-size compression.
Key capabilities
- Compress JPG, PNG, and WebP images
- Resize by exact pixel dimensions or by percentage
- Presets for common social-media and e-commerce sizes
- Quality controls for fine-tuned output
- Target a specific output file size in KB
- Choose the output format
- Works offline once the page has loaded
- Local browser processing — images never leave your device
Privacy and processing approach
Processing happens entirely in the browser using the Canvas API. Images are not uploaded to a server, so nothing you compress is stored or transmitted — the tool even works offline once loaded.
User workflow
Open the tool and drop an image onto the page, or browse to one on your device (up to 10MB).
Adjust pixel dimensions, percentage scaling, a preset, quality, output format, or a target file size in KB.
Review the live result and download the compressed image.
Design and engineering considerations
- A single obvious workflow: load an image, adjust, download.
- Instant visual feedback so changes are visible immediately.
- Clear, large controls that work on touch screens as well as desktops.
- Only the formats and options that matter, to keep the interface uncluttered.
Lessons and future improvements
- Privacy is a feature: local processing removes a major objection to using an online image tool.
- A focused tool beats a feature-packed one for repeat visitors who want one job done well.
- Future directions under consideration: batch processing, format-specific presets, and before/after comparison views.
