Feature overview

Feature Details
Supported inputs JPG, PNG, WebP, GIF and most common bitmap formats
Quality control Slider from 10–100 %; values around 75–85 % offer a good balance
Resizing Optional max width/height with aspect-ratio toggle
Output formats JPEG, PNG, WebP (choose the best fit for your use case)
Export Download or copy the result as a Data URL

How to use

  1. Drag an image onto the upload card or click to browse your files.
  2. Adjust the Compression quality slider. Lower numbers reduce size but may introduce artefacts.
  3. (Optional) Enable Resize before compression. Set maximum width/height in pixels and keep proportions with the checkbox if needed.
  4. Pick an Output format:
    • JPEG – universal support, ideal for photography.
    • WebP – smaller files for modern browsers.
    • PNG – lossless output with transparency.
  5. Hit Start compression and wait for the preview to update. The summary panel highlights the new size and savings.
  6. Download the optimised file or use Copy as Data URL to paste the encoded image into CSS, JSON or design tools.

Use cases

  • Boost page speed: compress hero banners and carousel assets before uploading to WordPress, Wix, Shopify or bespoke CMSs.
  • Optimise product listings: meet Amazon, Etsy or Mercado Libre size limits while keeping clean JPEG/WebP imagery.
  • Email and document sharing: shrink screenshots for newsletters, PowerPoint decks and customer support tickets that cap attachment size.
  • Prototype faster: drop the Data URL directly into Storybook, Tailwind config or React components during UI sprints.

Best practices

  • Aim for 80 %+ quality on photographic content to avoid heavy artefacts. Screenshots and UI assets often tolerate lower settings.
  • Resizing provides the biggest savings. If you only need a thumbnail, reduce the dimensions before tweaking quality.
  • WebP offers the best balance for web delivery; fall back to JPEG when targeting legacy browsers.
  • Everything happens on-device, so you can safely compress confidential visuals—no uploads, no tracking.

Troubleshooting

Why did the result look identical in size?
If the original image is already heavily compressed (e.g. a social-media JPEG), there may be little room for further reduction. Try resizing or switching formats.

Conversion failed for a huge file—what can I do?
Browsers have memory limits. Reduce the resolution in another tool first or process the file in smaller batches.

Need additional formats (HEIC, AVIF output)?
AVIF export requires the separate format converter tool. Other formats may need specialised WebAssembly codecs or server-side processing.
