A practical guide

Choose what “smaller” should mean for each image.

The general compressor handles JPG, PNG, and WebP in one local batch. It decodes each image, lets you keep its format or choose another, and shows the new size before you download. Quality affects JPG and WebP output; PNG uses the browser’s lossless encoder and ignores the quality slider.

A lower quality value can reduce photographic files substantially, but it may soften texture, introduce blocks around edges, or remove subtle gradients. Start near the default, inspect the preview, and move lower only when the smaller file matters more than fine detail. An already optimized image—or a PNG with complex pixels—may stay the same size or grow.

How to use it

From file to finished in four moves

Choose or drop up to 20 JPG, PNG, or WebP images. PixelShrink checks the real file signature and dimensions locally.
Keep the original format or select JPG, PNG, or WebP, then choose a quality level when the target supports it.
Run the batch and compare original size, output size, format, and preview for every successful file.
Download files individually or package the successful results into one ZIP made in your browser.

Format notes

Know what changes—and what does not.

JPG rewards sensible quality changes

Photographs usually tolerate moderate JPEG quality reduction better than screenshots or text-heavy graphics. JPG cannot preserve transparent pixels.

PNG size is content-dependent

PNG is lossless and excellent for transparency, interface captures, and flat graphics. Browser re-encoding is not guaranteed to make an existing PNG smaller.

WebP is built for the web

WebP can represent photos and transparency efficiently, but a publishing system or older workflow may still require JPG or PNG.

Good fits

Useful choices for real files.

A mixed blog upload

Compress a folder containing hero photos, transparent logos, and WebP thumbnails without forcing every file into the same format.

A portal with a file cap

Try a few quality levels and use the measured result—not a promise—to decide whether an image fits the portal’s limit.

Privacy by design

Your image does not become our file.

Selection, decoding, re-encoding, previews, and ZIP creation happen with browser APIs on this device. PixelShrink serves the application files, but your selected image bytes are not posted to the Laravel server. Ordinary page requests may still appear in hosting logs.

Frequently asked questions

Answers before you start.

Will every image become smaller?

No. The result depends on the source image, its existing optimization, the chosen format, and the browser encoder. Keep the original when the measured output is larger.

Does compression change the pixel dimensions?

This compressor keeps the decoded width and height. Use the resize tool when you also want fewer pixels.

Can I target an exact number of kilobytes?

Not reliably in one pass. Browser encoders accept a quality preference, not a guaranteed byte target, so compare the actual result shown for each image.
