Image Compressor (Reduce Size for Web, PNG/JPG/WebP)

Perfect for landing pages and newsletters: drop in multiple images, set your desired width, and grab a fresh ZIP optimized for web.

Shrink PNG/JPG/WebP files and export optimized assets instantly.

Compress PNG, JPG, and WebP images locally in your browser. Resize oversized images, export lighter JPEG or WebP files, and prepare batches for websites, ecommerce, docs, or social media without uploading source files.

How this page is maintained

  • Steps and copy are checked against the current tool behavior.
  • Browser limits, file-size constraints, or compatibility gaps are documented when relevant.
  • Unless a page explicitly says otherwise, files and text stay in the browser during processing.

When This Tool Is the Right Choice

Use this compressor when you already have finished images and need to make them lighter, faster, and easier to publish. Typical cases include blog hero images, product photos, screenshots for documentation, social graphics, email assets, and batches exported from design tools or a phone camera.

If you still need to crop, rotate, or redesign the image, do that first. Compression works best as the last optimization step before upload.

Practical Settings That Usually Work

Scenario Suggested output Suggested quality Suggested max width
Blog hero image WebP 72-80 1600-2000 px
Product photo JPEG or WebP 78-86 1600-2400 px
Documentation screenshot PNG or WebP 90+ for crisp text 1400-1800 px
Social media post JPEG 76-84 1080-1440 px
Email newsletter JPEG 68-78 1200 px
Internal draft JPEG 55-70 1200-1600 px

These are starting points, not hard rules. If text looks soft, raise quality or keep the width larger. If files are still too heavy, reduce width before crushing quality.

A Good Compression Workflow

  1. Remove images you do not plan to publish.
  2. Set a realistic max width instead of keeping a huge original just because it exists.
  3. Export one batch at a moderate quality first.
  4. Check the most detailed images at 100% zoom.
  5. Only push quality lower if you still need smaller files.

Common Mistakes

  • Compressing a tiny image again and expecting a huge size win
  • Saving screenshots as low-quality JPEG when text must stay crisp
  • Exporting every asset as PNG even when JPEG or WebP would be much smaller
  • Guessing blindly instead of adjusting width first

What This Tool Does and Does Not Do

It does batch-process files locally, resize oversized assets, and export lighter JPEG or WebP files in one go. It does not rewrite your site markup, replace CMS assets for you, or choose the perfect setting for every brand automatically. You still need to check the final result where the image will actually be used.

Privacy and Review Notes

All compression happens in the browser. That matters if the batch includes unreleased product shots, client work, internal screenshots, or personal photos. This page is maintained around real publishing workflows, not just the phrase "compress image online", so the guidance above is intended to help you make better tradeoffs instead of just producing smaller files.

Key features

  • Batch processing: Drag and drop dozens of images at once. The tool processes them in parallel using your device's CPU, making it faster than cloud uploaders for large batches.
  • Adjustable quality: Fine-tune compression levels (0-100) and resize large photos (e.g., max width 1920px) to hit exact file size targets for SEO.
  • Local privacy: Zero server uploads. Your personal photos, client assets, and unreleased designs never leave your computer. We use browser-native compression algorithms.
  • Next-Gen Formats: Convert heavy PNGs to lightweight WebP automatically to speed up your website's Core Web Vitals.

Frequently asked questions

What file types are supported?

We support PNG, JPG, and WebP inputs. You can export optimized files as JPEG or WebP (which is often smaller and faster).

Will the tool resize my images?

Yes. If you set a "Max width", images larger than that will be scaled down proportionally. This is great for creating thumbnails or standardizing blog assets.

Where do the files go?

Nowhere. Everything runs locally on your machine. When compression finishes, the tool generates a ZIP file directly in your browser memory for you to download.

Why use WebP?

WebP images are typically 25-35% smaller than comparable JPEGs, which means faster page loads and better SEO scores.

Is there a file size limit?

No hard limit. Since it runs on your device, it depends on your computer's RAM. Most modern devices can handle batches of 50+ photos easily.
