Image Compressor — Compress & Resize Photos in the Browser

Compress photos to an exact target size or convert between formats. Everything runs in your browser — your images never upload to a server.

How it works

  1. Select image — choose a photo from your device. HEIC, JPEG, PNG, WebP all supported.
  2. Set target size — drag the slider or type a number (e.g. 500KB, 1MB, 2MB). Real-time preview updates as you adjust.
  3. Convert format (optional) — pick JPEG, PNG, or WebP. The converter picks the best quality-to-size ratio.
  4. Download — one click. The compressed file stays in your browser until you download it; nothing is sent anywhere.

Compress images without uploading

Most online compressors require you to upload your photo to their server first. This one runs entirely in your browser. The image never leaves your device — the compression math happens locally, and only the final compressed file is returned to you.

This matters because: clients, screenshots, portfolio photos, and screenshots from work devices often contain sensitive information you don't want on a random server.

Steps

  1. 1

    Select an image

    Choose a photo from your device. Supports HEIC, JPEG, PNG, and WebP. Drag and drop or click to browse.

  2. 2

    Set target size

    Drag the slider or type a specific size (e.g. 500KB, 1MB, 2MB). The preview updates in real time.

  3. 3

    Convert format

    Optional: switch to JPEG, PNG, or WebP. The quality adjusts automatically to hit your target size.

  4. 4

    Download

    One click. The compressed file downloads to your device. Nothing was uploaded, nothing is stored.

Why this matters

Privacy first

Your photos never leave your device. No upload, no server, no storage. The compression algorithm runs in JavaScript inside your browser.

Fast & free

No account, no sign-up, no waiting. Open the page, compress, download. Instant.

No file size limits from a server

Server-based compressors cap you at what their infrastructure can handle. This one respects your device's capability.

Download anywhere

The compressed file is yours. Use it on your website, send it to a client, email it, or upload it wherever you need.
