Smart image compression with format conversion and batch processing. Reduce file sizes without losing quality.
Format and quality will be automatically optimized based on image analysis
• Use WebP for best compression with quality
• JPEG is ideal for photos, PNG for graphics
• 85% quality is usually indistinguishable from 100%
• Enable Smart Mode for intelligent optimization
Maximum file size: 10MB • Up to 50 images at once
Drag and drop up to 50 images at once, or click to browse. Supports JPEG, PNG, WebP, and other common formats. Each file can be up to 50 MB for free users or 100 MB for premium.
Select from quality presets: Maximum Quality retains near-perfect clarity, Balanced offers the best size-to-quality ratio, and Maximum Compression prioritizes the smallest possible file size.
Use the side-by-side comparison view to see the difference between your original and compressed image. The file size reduction percentage and new dimensions are displayed for each file.
Download individual files or batch download everything as a zip. Each image shows its compression ratio so you know exactly how much space you saved.
The tool analyzes each image's content and applies the optimal compression strategy. Photos get different treatment than graphics or screenshots, maximizing savings without visible artifacts.
Compress entire galleries, product catalogs, or blog image libraries in one operation. All files are processed in parallel for maximum speed.
A side-by-side grid view in a modal lets you compare the original and compressed versions. Verify quality is preserved where it matters before downloading.
Optionally convert to a more efficient format during compression. Switching a JPEG to WebP while compressing can achieve file size reductions of 60-90%.
Optionally set a maximum width or height to resize images during compression, reducing both dimensions and file size in a single step.
All compression runs in your browser. Images are not uploaded anywhere, so your proprietary visuals, product photos, and client work remain confidential.
Website owners compress images to improve page load speed and Core Web Vitals scores. Images are typically the heaviest assets on a webpage, and reducing their size by 50-80% can shave seconds off load times. Faster pages rank better in Google search results and convert more visitors into customers.
Email marketers compress images to stay within email size limits and ensure messages load quickly on mobile devices. Most email clients block images by default until the user opts in, and when they do, oversized images that take seconds to load get ignored. Compressed images load instantly and keep readers engaged.
App developers and game designers optimize sprites, textures, icons, and UI assets to reduce app bundle sizes. Smaller apps download faster, use less storage on users' devices, and face fewer installation abandonment issues. The batch processing feature handles hundreds of assets efficiently.
Typical reductions range from 40% to 90% depending on the image type and chosen quality level. Photographs compress well with lossy algorithms, while PNG graphics with large areas of flat color can see dramatic savings with lossless optimization. The tool shows the exact reduction for each file.
At the Balanced and Maximum Quality presets, compression artifacts are virtually invisible to the human eye. The before/after comparison tool lets you verify quality at pixel level before downloading. You can always increase the quality slider if you notice any degradation.
Lossy compression discards some image data that is imperceptible to most viewers, achieving much smaller file sizes. Lossless compression reorganizes the data without discarding anything, resulting in smaller but less dramatic savings. PNGs use lossless compression, while JPEGs and WebP use lossy by default.
Yes, PNG compression in this tool is lossless and preserves the alpha channel completely. Transparent areas, semi-transparent effects, and the overall image quality remain identical. File size reductions come from optimizing the internal encoding, not from removing pixel data.
Free users can compress up to 3 images per day with a 50 MB per-file limit. Premium users get up to 1,000 images per day with a 100 MB per-file limit. Since processing happens in your browser, there is no server queue or waiting time.
