Compress Images Without Uploading

Make photos small enough for email, forms and websites. Choose a compression level and an optional max size — then compare the before and after file sizes.

How to compress an image

  1. 1

    Add images

    JPG, PNG, WEBP or HEIC — one or many.

  2. 2

    Choose strength and size

    Recommended plus 1920 px suits most email and web uses.

  3. 3

    Compress and compare

    Each file shows its new size and how much you saved.

Which settings should I use?

  • Email or messaging: Recommended + 1920 px. A 4 MB phone photo usually ends up around 300–600 KB.
  • Job or government upload forms with a 1 MB / 500 KB limit: Strong + 1920 px, or 1280 px for very strict limits.
  • Website images: WEBP + Recommended + 2560 px or less.
  • Keep printing quality: Light, keep dimensions.

Resizing saves far more than heavier compression: halving the width cuts the pixel count by 75%.

Private compression

Your file is opened by your own browser and converted on your device. Nothing is uploaded, so there is no queue, no file-size quota and no copy left on someone else's server. You can even disconnect from the internet after the page has loaded and the conversion still works.

Frequently asked questions

Phone photos typically shrink 70–90% with Recommended + 1920 px. Already-optimised images may barely change; in that case we keep your original.

Yes. The output is a freshly encoded image, so metadata such as GPS location and camera details is not carried over.

Output is JPG or WEBP, which compress far better than PNG. If you need transparency, choose WEBP.

No. Compression happens in your browser on your own device.

Doing this on an iPhone every day?

This page works in Safari on iPhone, so you never need an app for a one-off conversion. If you convert photos regularly, the ConvertEase app does it natively: pick images from your library, choose JPG, PNG, GIF, BMP or TIFF, and the conversion runs on the phone itself.

The app is free to download; saving results requires a ConvertEase Premium subscription. This web tool stays free.
