Introduction
Digital images often contain more data than necessary for web delivery. Compression removes perceptually redundant information, producing substantially smaller files while preserving visible detail and color fidelity. Faster loading images improve user experience, lower bandwidth costs, and reduce storage demands across websites, emails, and mobile apps. The process relies on adaptive encoding that balances quality against file size.
This tool executes every compression step within your browser using a high-performance compression engine and a reactive interface. Adjustable sliders, format selectors, and optional dimension fields let you fine-tune output without refreshing the page. Real-time calculations display estimated space savings, helping you decide the best compromise between fidelity and file size before downloading the result.
Use it to prepare product photos or social media banners for quick online sharing in seconds. Avoid overwriting originals until you confirm result quality.
Technical Details:
Under the hood, the component leverages modern browser APIs, including File, Canvas, and WebAssembly, to decode the source image, apply lossy or lossless compression, and re-encode it on the client. No pixel data leaves the device, so privacy is inherently protected.
Interactive controls are bound through a lightweight state-management layer. Whenever you adjust quality, format, or dimensions, an asynchronous worker recompresses the original blob on supported browsers and returns a fresh preview accessed via a revocable object URL, ensuring memory is reclaimed promptly after each iteration.
Feature Breakdown
Drag-and-Drop Upload
Drop an image onto the interface or click to browse; the tool immediately reads the file and displays status updates.
Live Quality Control
A slider lets you set compression quality from 10-100 %; changes trigger instant re-compression and preview refresh.
Format Conversion
Choose JPEG, PNG, or WebP output; the engine re-encodes accordingly, letting you adopt modern formats for extra savings.
Metadata Handling
Toggle EXIF preservation to keep or discard camera data, ensuring personal details stay private when sharing online.
Dimension Resizing
Optional width and height limits downscale images before compression, preventing oversized uploads and saving even more space.
Instant Download Link
After processing, a secure object URL and one-click button deliver the compressed file without further dialogs or redirects.
Step-by-Step Guide:
Follow these steps to compress and download your image efficiently.
- Drag & drop a file into the Source Image panel or click to browse.
- Adjust the Quality slider until the displayed saving percentage meets your goal.
- Select your preferred output Format (JPEG, PNG, or WebP).
- Expand the Advanced section to fine-tune EXIF, orientation, and dimension options.
- Review the preview and statistics table to verify size reduction.
- Press Download to save the compressed file, or Reset to start over.
FAQ:
Find quick answers to common questions below.
Is my data stored?
No. All processing happens locally in your browser; the image never leaves your device.
Why did the file size barely change?
High-quality or already optimised images offer less redundant data. Lower the quality slider or convert to WebP for greater savings.
Does compression reduce resolution?
No, unless you set maximum width or height values. Without resizing, only file size and compression artefacts change.
What happens to EXIF information?
If “Preserve EXIF metadata” is unchecked, camera details and GPS tags are removed to protect privacy.
Can I batch compress images?
The current version handles one image at a time. Repeat the process for additional files.
