How to compress an image online

  1. Add your images

    Drop JPEG, PNG, or WebP files onto the tool, click to browse, or paste straight from your clipboard. You can queue a whole batch at once.

  2. See the results

    Compression starts automatically the moment images are added. Each one is processed locally in your browser, one after another, with per-file progress and savings shown as it goes.

  3. Refine the size target

    Switch between Smallest (about 200 KB), Balanced (about 500 KB), and Best quality (about 2 MB) and the whole batch re-compresses instantly. Open any thumbnail to compare the original against the compressed result.

  4. Download

    Save images individually or grab the whole batch as a single ZIP. Compressed files keep their original format.

Why use this tool

Nothing leaves your browser

Compression runs locally in your browser. Your images are never uploaded to a server, so private photos stay private.

Batch compression with ZIP download

Queue any number of images, compress them in one run, and download everything as a single ZIP archive.

Size targets, not abstract percentages

The three presets aim at real-world caps of roughly 200 KB, 500 KB, and 2 MB per image, so results actually fit email and CMS limits.

Keeps the original format

JPEG stays JPEG, PNG stays PNG, WebP stays WebP. Nothing downstream breaks because a file quietly changed type.

Free, no signup, no watermark

No account, no daily quota, no branding stamped on your files.

About this tool

This image compressor reduces JPEG, PNG, and WebP file sizes directly in your browser. Instead of asking you to guess what a quality percentage means, it targets a file size: pick roughly 200 KB for the smallest files, 500 KB for a balance that suits most web pages, or 2 MB when detail matters more than weight. Images longer than 4000 pixels on their longest side are also scaled down, which is plenty for any screen and often where the biggest savings hide.

Smaller images matter in practice: email providers cap attachments, CMS and forum uploads enforce per-file limits, and oversized photos are one of the most common reasons a page fails Core Web Vitals. Because the tool processes a whole batch sequentially and shows per-file savings, it suits jobs like shrinking a folder of listing photos or preparing screenshots for documentation, then handing everything back as one ZIP.

Compression happens entirely on your device, which is the boring but important part: product mockups, ID scans, and family photos never touch a server. If you need exact pixel dimensions instead of a file-size target, use the image resizer; to switch a file between JPEG, PNG, and WebP, use the image format converter.

Frequently asked questions

How much can I shrink an image with this tool?
JPEGs typically shrink by 30 to 80% with a small quality drop. PNGs shrink less, depending on how much detail and how many colours they contain. The exact savings depend on the image and the quality level you choose.
Does compressing an image lose quality?
JPEG and WebP compression is lossy by design. Every save loses a little detail. The size target controls how aggressive that loss is. PNG compression is lossless: smaller file, same pixels.
Are my images uploaded somewhere?
No. Compression happens entirely in your browser. Your file is never sent to a server.
What file types are supported?
JPEG, PNG, and WebP. The output keeps the same format as the input. To convert between formats, use the image format converter.
Is there a file size limit?
There is no enforced limit, but very large images (>50 MB) can be slow because compression runs in your browser. Try one image at a time for the best experience.
