Free Online Image Compressor & Resizer
Large image files slow down websites, consume storage space, and use up mobile data. Our free online image compressor reduces file size dramatically — typically 60-90% — while maintaining visual quality that is indistinguishable to the human eye. No file uploads to a server: all compression happens directly in your browser using the Canvas API and WebP encoding.
Supports JPEG, PNG, WebP, GIF, and BMP input formats. Compress a single image or batch-process multiple images at once. Resize by pixels or percentage, control compression quality, and download individually or as a ZIP archive. Your images never leave your device.
How to Compress Images Online
- 1
Upload your images
Click the upload area or drag and drop one or multiple image files. Supports JPEG, PNG, WebP, GIF, and BMP. You can upload up to 20 images at once for batch processing.

Set compression quality
Use the quality slider (1-100) to control the trade-off between file size and image quality. 70-85 is the sweet spot for most web images — excellent quality at a fraction of the original size.

Resize dimensions (optional)
Set a maximum width or height in pixels, or resize by percentage. The tool maintains the original aspect ratio automatically. Leave blank to keep the original dimensions.
- 4
Choose output format
Select JPEG for photographs (smallest file size), PNG for images requiring transparency, or WebP for the best quality-to-size ratio on modern browsers.

Download compressed images
Preview the compressed images with the before/after size comparison. Download individual files or click "Download All" to get a ZIP archive of all compressed images.
Why Compress Images?
Website Performance
Images account for 50-70% of a typical webpage's size. Compressing them dramatically improves page load speed, which directly impacts SEO rankings and user experience.
Email Attachments
Email clients limit attachment sizes (typically 10-25MB). Compress photos before attaching to ensure they send reliably and don't fill your recipient's inbox.
Social Media Upload
Most platforms (Instagram, Twitter, LinkedIn) further compress images on upload. Pre-compressing with our tool gives you control over quality before platform compression degrades your images.
Cloud Storage Savings
Reduce storage costs on Google Drive, Dropbox, or cloud hosting by compressing photos before uploading. Compressed images take less space without visible quality loss.
E-commerce Product Images
Optimize product images for fast-loading online stores. Faster pages improve conversion rates — a 1-second delay reduces conversions by approximately 7%.
Mobile App Assets
Optimize UI images, icons, and illustrations for mobile apps. Smaller assets mean faster app load times, lower data usage for users, and smaller app store download sizes.

Image Compression & Core Web Vitals
Google's Core Web Vitals — particularly Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS) — are directly impacted by image optimization. Properly compressed and sized images improve your LCP score (how quickly the main content loads) and prevent layout shifts from images loading with wrong dimensions. Google uses Core Web Vitals as ranking signals, making image compression an essential SEO practice.
