Free Image Tools for Your Browser
Compress, resize and convert images or remove backgrounds with simple tools that run directly in your browser.
Your images are processed locally. They are not uploaded to an Optimaza image-processing server or stored online by Optimaza.
Drag and drop images here
Up to 10 JPEG or PNG files. Compression happens in your browser.
You can also drop files here.
One place for everyday image tasks
Optimaza brings common image workflows into one privacy-first browser toolkit. Use it when you need smaller files, different formats, fixed dimensions or a transparent-background PNG without opening a heavy editing app.
The working tool stays at the top of the page, so you can start with JPEG compression and switch to another tool when your task is different.
What can you do with Optimaza?
| Task | Tool | Useful when |
|---|---|---|
| Reduce photo file size | Compress JPEG | You need lighter JPG files for websites, email or sharing. |
| Optimize PNG graphics | Compress PNG | You want smaller PNG files while keeping transparency. |
| Fit images to maximum dimensions | Resize Image | Large images need to fit layout, upload or message limits. |
| Convert JPEG to PNG | JPEG to PNG | Your workflow needs a PNG copy of a JPEG image. |
| Convert PNG to JPEG | PNG to JPEG | You need a JPG file and transparent pixels can be flattened to white. |
| Remove an image background | Remove Background | You need a transparent PNG cutout from a JPG or PNG image. |
Why process images in the browser?
Many online image workflows send a file to a remote server, process it there and then return a result. Optimaza is built around supported processing that happens locally in your browser.
That makes quick image tasks more direct: add images, choose the tool, review the output and download the result without sending the image to an Optimaza image-processing server.
Private by design
Optimaza processes supported images locally in your browser. The app does not store your source images online, and the image tools do not require an account.
Compression, resizing and conversion are different
- Compression reduces file size while keeping the same visual dimensions.
- Resizing changes pixel dimensions by fitting large images within your maximum width or height. Smaller images are not enlarged.
- Conversion changes the file format, such as JPEG to PNG or PNG to JPEG.
- Background removal separates the subject from the background and exports a transparent PNG.
How to use Optimaza
- Choose the image tool that matches your task.
- Add up to 10 supported images from your device.
- Adjust settings when the selected tool offers them.
- Process the images in your browser.
- Download one result or download all finished files.
Which image tool should I use?
| If you need to | Use | Why |
|---|---|---|
| Make JPG photos smaller | Compress JPEG | JPEG quality can be adjusted to balance size and visual quality. |
| Make transparent graphics smaller | Compress PNG | PNG optimization keeps the PNG format and preserves transparency. |
| Change image width or height | Resize Image | Resize fits JPG, PNG and WebP images inside your chosen dimensions. |
| Create a PNG copy from a JPEG | JPEG to PNG | The converter exports a PNG version in the browser. |
| Create a JPEG from a PNG | PNG to JPEG | The converter exports JPEG and fills transparent areas with white. |
| Get a transparent background | Remove Background | Background removal exports a transparent PNG. |
Prepare images for the web
Large images can add unnecessary page weight. Compression can reduce file size, resizing can prevent oversized dimensions, and conversion can help when a platform expects a specific file type.
Image optimization can support better web performance, but real page speed and SEO depend on many factors beyond image files alone.
Built for simple, repeatable image tasks
Optimaza is made for everyday production work: product photos, images for messages, website dimensions, format conversion and transparent-background PNG files.
You can process up to 10 images in one batch, download individual results or download all finished files. No account is required.
Current image tools and formats
| Tool | Input | Output | Notes |
|---|---|---|---|
| Compress JPEG | JPEG, JPG | JPG | Uses JPEG quality settings and can fit images to maximum dimensions. |
| Compress PNG | PNG | PNG | Strips selected metadata, re-encodes PNG data and preserves transparency. |
| Resize Image | JPG, PNG, WebP | Same format | Keeps aspect ratio, does not upscale smaller images and uses 92% quality for JPG/WebP export. |
| JPEG to PNG | JPEG, JPG | PNG | Creates a PNG copy in the browser. |
| PNG to JPEG | PNG | JPG | JPEG has no transparency, so transparent pixels are flattened to white. |
| Remove Background | JPG, PNG | PNG | Runs local background removal and exports a transparent PNG. |

Frequently asked questions
What is Optimaza?
Optimaza is a collection of browser-based image tools for compression, resizing, conversion and background removal.
Is Optimaza free to use?
Yes. Optimaza is free to use.
Do I need to install software?
No. Optimaza runs in a modern browser, so you do not need to install image-editing software.
Do I need an account?
No. The image tools can be used without creating an account.
Are my images uploaded to a server?
No. Supported image processing runs locally in your browser instead of uploading files to an Optimaza image-processing server.
Which formats does Optimaza support?
Optimaza currently includes tools for JPEG/JPG, PNG and WebP workflows. Supported formats depend on the selected tool.
Can I process multiple images at once?
Yes. Supported tools can process up to 10 images in one batch.
What is the difference between compression and resizing?
Compression reduces file size. Resizing changes pixel dimensions by fitting an image within width or height limits.
Does resizing keep the aspect ratio?
Yes. Resize Image keeps the original aspect ratio and does not enlarge smaller images.
What happens when I convert between JPEG and PNG?
JPEG to PNG creates a PNG copy. PNG to JPEG creates a JPG file and fills transparent areas with white because JPEG does not support transparency.
What output does background removal create?
Background removal accepts JPG and PNG images and exports a transparent PNG.
Which tool should I use to make an image smaller?
Use Compress JPEG for JPG photos, Compress PNG for PNG files, or Resize Image when the image dimensions are larger than needed.
