Image Compressor

Compress and resize images in your browser. Fix EXIF rotation, control quality, set target size or max dimensions, and export as JPEG/PNG/WebP — or ZIP everything.

Drag & drop images here, or
JPEG, PNG, WebP, GIF (first frame), SVG (rasterized by the browser).

0 = keep original

0 = keep original

Auto uses WebP when smaller (keeps alpha), else JPEG.

0.80

0 = ignore (use quality). We’ll try to get close.

How it works

1) Add images

Drop files or pick from disk. We process them locally in your browser.

2) Tune output

Set max dimensions, quality, target KB, and output format. EXIF rotation is fixed automatically.

3) Export

Download each image or a ZIP. For huge batches, use “Process via backend”.

Image Compression: Formats, Quality & Best Practices

When to choose JPEG vs WebP vs PNG, how quality affects size, and tips for clean downsizing.

Formats

  • JPEG: best for photos; small sizes, no alpha channel.
  • WebP: modern and small; supports transparency; widely supported.
  • PNG: lossless; ideal for UI, logos, and images with sharp edges/transparency.

Quality & target size

Quality is a 0–1 slider; lower values make smaller files but can introduce artifacts. If you must hit a budget, set a Target size and we’ll iterate quality to get close.

Resizing rules

We maintain aspect ratio and cap images to the chosen max width/height. For web, 1920×1080 usually suffices for hero images; thumbnails can be 320–640 px wide.

EXIF orientation

Some cameras save photos “sideways” with an EXIF Orientation flag. We normalize the pixels so your exported file looks correct everywhere.

FAQ

Does PNG quality do anything?

Browsers don’t expose PNG compression levels via canvas; choose WebP or JPEG for smaller output if quality allows.

Will metadata be preserved?

Canvas exports typically strip EXIF/IPTC. Use the backend if you need fine-grained control.
