We optimize media files: JPEG and PNG images
Upload up to 10 images and optimize them in seconds. Compression starts automatically after upload.
All processing runs entirely in your browser — your files stay private. You can fine-tune the compression percentage in the menu. You can also set a max width or height to fit images.
Download optimized images individually or save everything at once.
Overview
This tool optimizes images directly in the browser without uploading files. Optimaza is a browser-based image optimizer that reduces file size for JPEG/JPG photos and PNG graphics, making them faster to load and easier to share.
Image optimization means removing unnecessary file size while keeping the picture visually useful. It helps improve website performance, speed up image delivery, and reduce storage usage.
Why image optimization matters
Smaller images load faster, which improves page speed and user experience. Faster pages can also help SEO, since search engines consider performance signals.
Optimized images are easier to send and store. Whether you’re sharing in chats, uploading to a website, or attaching files to email, smaller files save time and bandwidth.
How image optimization works
The tool reprocesses image files to reduce size while keeping them visually useful. For JPEG/JPG, this typically means adjusting compression. For PNG, optimization focuses on keeping transparency while reducing excess data.
Everything happens locally in your browser using client-side processing. Files are not uploaded, stored, or shared.
How to use this tool
Choose the format tab (JPEG/JPG or PNG) depending on your images.
Upload up to 10 images at once by dragging files into the upload area or selecting them from your device.
Compression starts automatically after upload.
Download optimized images individually or save everything at once.
Resize images by setting a max width or height (fit to size). This can reduce file size for web, email, and sharing; smaller images are not upscaled.
Optional control
You can fine-tune the compression percentage in the menu to balance file size and visual quality for faster loading and better Core Web Vitals.
Typical results
Results vary by image content, format, and original size. Photos with lots of detail usually show noticeable size reduction, while simple graphics may change less.
As a rule of thumb, optimization often reduces file size without visibly changing the image for normal viewing. Always review outputs if you need strict visual accuracy.
Privacy and security
This tool runs entirely in your browser. Your images never leave your device, and nothing is uploaded, stored, or shared.
Because processing is local, you keep full control over your files at all times.
