Free image compressor

Shrink your images without shrinking their quality

Drop in JPG, PNG or WebP files and ShrinkPix compresses them right in your browser — no uploads, no accounts, no waiting on a server.

Drag & drop images here, or click to browse

JPG, PNG, WebP · up to 25MB each · processed on your device only

How it works

ShrinkPix uses your browser's own graphics engine to re-encode images, the same technology behind photo editing apps — just running quietly in a tab instead of on a server.

01

Choose your images

Drag files into the box above, or click it to pick photos from your device. Add as many as you like in one go.

02

Set your quality

Adjust the quality slider and output format. Lower quality gives smaller files; the preview size updates instantly per image.

03

Download the result

Save individual files or grab everything at once. Nothing is stored on our servers — once you close the tab, it's gone.

0server uploads required

Private by design

Most online compressors send your photos to a server before returning a smaller file. ShrinkPix skips that step entirely — the compression happens in your browser's canvas engine, so screenshots, ID photos, or client work never travel over the network.

<1stypical processing time

Fast, even in bulk

Because there's no upload queue or server to wait on, most photos compress in well under a second. Batches of dozens of images still finish in moments on a typical laptop.

3formats supported

JPG, PNG and WebP

Compress within the same format, or convert to WebP for the smallest possible file size while keeping images sharp enough for web and social use.

Which format and quality should you pick?

A short guide so you get a small file without visibly hurting the picture.

Choosing a format

  • JPG — best for photographs. Small files, but lossy: every re-save loses a little detail, and it can't do transparent backgrounds.
  • PNG — best for logos, icons, screenshots and anything with transparency or sharp text. Lossless, so photos saved as PNG are often several times larger than the same photo as JPG.
  • WebP — usually the smallest option for both photos and graphics, and supported by all current browsers. Some older design software still can't open it.

Choosing a quality level

  • 60–70 — thumbnails, backgrounds and images shown small. Biggest savings, and the loss is rarely noticeable at that size.
  • 75–85 — a good default for blog and article photos. File size drops a lot while the picture still looks the same on a normal screen.
  • 85–92 — product photos or anything a visitor might zoom into, where compression blotches would be easier to spot.

Three habits that save the most space

  1. Resize first. A phone photo is often 3,000–4,000 pixels wide, far more than a web page ever shows. Setting a maximum width before compressing usually saves more than lowering quality.
  2. Keep your original. JPG and WebP are lossy, so always compress from the untouched original rather than re-compressing an already compressed copy.
  3. Check the result at 100% zoom before you publish. If you can't see a difference, the smaller file is the right one.
  4. Why file size matters

    Images are usually the heaviest part of a web page. Oversized ones slow loading, which costs visitors on mobile connections and can affect how a page performs in search. Compressing images before uploading them to a website, an email or a form with an upload limit is one of the quickest fixes available.

Common questions

Is ShrinkPix really free?

Yes. There's no sign-up, file limit trickery, or watermark. The tool is supported by the advertising you see around the page, not by charging for compression.

Do you store or see my images?

No. Compression runs entirely in your browser using the HTML5 canvas API. Your files are never transmitted to our servers or any third party — see our Privacy Policy for details.

Why did my PNG barely get smaller?

PNG is a lossless format, so there's a limit to how much re-encoding alone can shrink it. For the biggest size reduction on photos saved as PNG, switch the output format to WebP or JPG.

What's the maximum file size or number of images?

You can compress files up to 25MB each, and there's no fixed limit on how many you add per batch — performance depends on your device's memory.
