One place for files that need to fit

Optimize images and PDFs without installing an app. Every tool runs in your browser and needs no account.

Have a specific size limit?

Application portals often ask for an exact size. Pick a target below and start with the value already filled in.

Built for results you can use right away

Not just smaller files. These tools help you meet upload limits without giving up more quality than necessary.

Your files stay put

There is no upload API. Everything runs in browser memory and disappears when you close the tab.

KB and MB precision

Set a target and let the tool find the best quality and resolution that still fits.

Many files at once

Track each image, cancel a run, and download every result in a single ZIP.

Full control over PDFs

Merge, rotate, delete, and reorder pages. Then reduce the result to a target size if needed.

No server queue

Speed depends on your device, not on upload queues. Nothing waits in a remote processing line.

Free and account-free

No sign-up, no hidden daily limits, and no watermark on your results.

How it works

Three simple steps, all in your browser.

  1. Choose a file

    Drag and drop, browse your device, or paste an image from the clipboard.

  2. Set the result

    Use automatic mode, adjust quality manually, or enter a KB/MB target.

  3. Download

    Save files one by one or download everything as a ZIP — no queue.

See the difference

Drag the divider to compare the original image with its compressed version. Details stay sharp while the file gets much smaller.

A real example: the photo was compressed by the image compressor on this device.

Frequently asked questions

The questions people ask most before using these tools.

Contact
Are my files uploaded to a server?
No. Every image and PDF is processed in your browser using Web Workers and canvas. The server only delivers the web page; your files are never sent, stored, or viewed by us.
How does a 100 KB target work?
In target mode, the tool tests multiple quality and resolution levels, then keeps the best result that fits under the limit. If the target is very small, image resolution is lowered in steps, and you will see a warning if the target still cannot be reached.
Which file formats are supported?
Images: JPG, PNG, WebP, BMP, and static GIF; HEIC may work depending on browser support. PDF: standard documents without password protection. Output can be JPG, PNG, or WebP.
Are there file count or size limits?
To protect browser memory, each image is limited to 50 MB and each PDF to 100 MB. Image and PDF queues are limited to 20 files. Large PDFs are processed page by page to keep the tab stable.
Can I use these tools on a phone?
Yes. The interface is mobile-first, supports touch drag and drop, and all buttons are at least 44 pixels tall. Processing still happens on your device, so speed depends on your phone’s capabilities.
Can compressed PDFs still be edited?
It depends on the mode. PDF compression and re-rendering turn pages into images, so text cannot be selected or searched. In PDF Page Optimizer, choose Keep original structure if you need text and links to stay intact.
