TinyPNG / TinyJPG
Third-party cloud image compression service for WebP, PNG, and JPEG formats by Voormedia.
Free web tier: 20 images/batch (5MB each); Web Pro: $39/year per user for 75 images/batch up to 75MB; API: First 500 compressions/month free, then $0.009 to $0.002 per image.
What is TinyPNG / TinyJPG (TinyJPG / TinyPNG) and How Does It Compress Images?
TinyPNG (and its sister portal TinyJPG, known together as tinypng/tinyjpg or tinyjpg/tinypng) is an online image compression service created by Voormedia B.V. When you upload a picture to tiny png or tinyjpg, similar colors are combined through selective color quantization. By converting 24-bit RGB files with millions of colors into 8-bit indexed color images with a tightly optimized palette, redundant color data is eliminated. The visual difference is practically invisible to the human eye, but it shrinks file sizes by 60% to 80% while preserving full alpha channel transparency. Whether you search for the official brand or common typos like tinyong or tyni png, this panda tool remains the global standard for fast, high-quality compression.
How to Shrink PNG and JPEG Picture Size with TinyPNG / TinyJPG (TinyJPG Free)
Upload Your PNG, JPEG, or WebP Files
Visit TinyPNG.com or TinyJPG.com (tinypng/tinyjpg). Drag and drop up to 20 PNG, JPG, or WebP files into the designated drop zone marked with the panda mascot. Each file can be up to 5MB on the tinyjpg free tier.
Automatic Intelligent Online Compression
The panda image compressor (tiny png) immediately analyzes each photo. The algorithm analyzes color distribution, quantizes color palettes, removes superfluous EXIF metadata, and minimizes file weight without blurring edges.
Review File Size Savings & Download
Watch the real-time progress bar show percentage savings (e.g. -72% reduction). Download your compressed files individually or click "Download all" to save a consolidated ZIP archive.
- To decrease PNG file size even further, convert photographic PNGs to modern WebP before running tinyjpg/tinypng compression.
- For UI screenshots and logos with transparent backgrounds, tiny png achieves massive reductions exceeding 75% while keeping typography pin-sharp.
- If an image exceeds the 5MB upload limit on the tinyjpg free plan, crop or resize dimensions slightly using a free online tool before running it through TinyPNG.
Core Features of TinyPNG / TinyJPG (TinyJPG / TinyPNG)
TinyPNG combines simplicity for everyday users with developer-grade automation tools and a robust tinyjpg free online service.
Smart Lossy Palette Quantization
Identifies visually redundant color nuances and maps millions of colors into a tightly indexed palette without introducing unsightly color banding.
Full Alpha Transparency Preservation
Unlike older GIF compression, tiny png retains full 8-bit gradient alpha transparency so drop shadows and transparent borders blend seamlessly on any website background.
TinyJPG Free JPEG Shrink & WebP Compression
Applies tailored DCT frequency quantization on JPEGs and entropy coding on WebP to minimize byte weight while maintaining photographic realism.
Dual Engine Accessibility (tinypng/tinyjpg & tinyjpg/tinypng)
Both web interfaces share the same underlying Voormedia algorithms, ensuring identical compression quality regardless of which portal you use.

Technical Guide: How TinyPNG Shrinks PNG & JPEG Files
Why PNG Files Are Typically Heavy & How Quantization Shrinks Them
Standard PNG-24 stores 8 bits per channel for Red, Green, and Blue, plus 8 bits for Alpha (transparency), requiring 32 bits per pixel. For a 2000x2000 image, uncompressed raw pixel data equals 16 megabytes before DEFLATE compression. TinyPNG converts this to PNG-8 with indexed colors, slashing the byte count by mapping pixels to a 256-color palette. Because the human eye is far less sensitive to tiny chrominance shifts than luminance shifts, the visual output looks virtually identical to the original.
PNG to WebP and Compress: When to Convert Formats
Modern browsers universally support WebP and AVIF. If your goal is to shrink picture size for website performance, converting PNG to WebP and running compression often cuts file size by an extra 30% over optimized PNGs. However, if you need maximum compatibility with legacy design software, keeping a compressed PNG with full alpha channel transparency via tinypng/tinyjpg is the most versatile solution.
Frequently Asked Questions: TinyPNG / TinyJPG
Direct answers regarding safety, usage, limits, and technical details.
TinyPNG and TinyJPG (often written as tinyjpg/tinypng or tinypng/tinyjpg) are the exact same underlying service developed and operated by Voormedia B.V. Both websites accept PNG, JPEG, and WebP files and run the exact same intelligent lossy compression algorithm. TinyPNG was originally launched specifically for PNG files and TinyJPG for JPEG photos, but today both domains handle all major web graphic formats with equal efficiency.
