Large image files slow down your website, eat mobile data, and hurt your Google rankings. Our free Image Compressor lets you shrink images by up to 90% in seconds — right in your browser. Here is exactly how to use it.
Step 1: Open the Image Compressor
Go to pixelforge.com/image-compressor. No account, no login, no software to install. The tool runs entirely in your browser, meaning your images never leave your device.
Step 2: Upload Your Images
You have two ways to add images:
- Drag and drop — drag one or multiple image files directly onto the upload area
- Click to browse — click the "Choose Files" button and select files from your computer
Supported formats: JPEG, PNG, and WebP. You can upload multiple files at once for batch compression.
Step 3: Set Your Quality Level
Use the Quality Level slider to control the balance between file size and image quality:
- 80% (recommended) — virtually no visible quality loss, significant file size reduction
- 60–70% — smaller files, minor quality reduction visible only on close inspection
- 90–100% — near-original quality, moderate size reduction
- Below 50% — very small files, noticeable quality loss — only for thumbnails
💡 Tip: For most websites, 75–85% quality gives the best balance. Visitors cannot tell the difference but your pages load much faster.
Step 4: Choose Output Format
Select your desired output format:
- JPEG — best for photographs, smallest file sizes
- PNG — best for graphics, logos, and images with transparency
- WebP — modern format, 25–34% smaller than JPEG at same quality, supported by all modern browsers
- Keep Original — outputs in the same format as your input
Step 5: Compress
Click the "Compress Images" button. Compression happens instantly in your browser — no waiting for uploads or server processing.
Step 6: Review Results and Download
After compression, you will see:
- A thumbnail preview of each compressed image
- Original size vs. compressed size comparison
- Percentage saved (e.g., "-72%")
- Total stats across all files
Click "Download" next to each file to save it. Files are named automatically with "_compressed" appended.
How Much Can You Compress?
Typical compression results:
- JPEG photo (3MB) → 300–600KB at 80% quality = 80–90% reduction
- PNG screenshot (1MB) → 200–400KB = 60–80% reduction
- WebP image → already optimised, gains of 20–40% still possible
Frequently Asked Questions
Is there a file size limit?
Each file can be up to 10MB. For larger files, consider resizing the image first using our Image Resizer to reduce dimensions before compressing.
Are my images sent to a server?
No. All compression happens in your browser using JavaScript. Your images are never uploaded anywhere. 100% private.
Can I compress multiple images at once?
Yes! Select multiple files in the file picker or drag several files at once. The tool processes them all in a batch.
Will compressed images look different?
At quality settings of 75% and above, the difference is imperceptible to the human eye. We recommend always spot-checking compressed images before publishing.
