About JPG Compression
JPG (JPEG) is the most widely used image format for photographs. Our compressor uses intelligent algorithms to reduce file sizes while preserving visual quality.
How JPG Compression Works
- Optimized Encoding: Quality 85 with trellis quantization and optimized scan patterns for maximum compression without visible quality loss.
- Progressive Encoding: Images are saved in progressive format for faster web loading.
- Metadata Stripping: EXIF data is removed to reduce file size (location data is always removed for privacy).
- Chroma Subsampling: Color information is optimized where the human eye is less sensitive.
Best For
Photographs, complex images with gradients, and any image where some quality loss is acceptable for smaller file sizes.
Frequently Asked Questions
How do I reduce JPG file size without losing quality?
Our JPG compressor uses state-of-the-art encoding algorithms including trellis quantization and optimized scan patterns to maximize compression while preserving visual quality. For most photos, you'll see 40-80% size reduction with no visible difference. The key is advanced encoding techniques that remove data the human eye can't detect.
What's the difference between JPG and JPEG?
Nothing! JPG and JPEG are exactly the same format. The only difference is the file extension. JPEG stands for Joint Photographic Experts Group (the committee that created the format). Windows historically used 3-character extensions (.jpg), while other systems used .jpeg. Our compressor accepts both.
Why are my JPG photos so large?
Large JPG files usually come from: 1) High-resolution cameras (modern phones shoot 12-48MP), 2) Minimal initial compression (cameras prioritize quality), 3) Embedded metadata (EXIF data, color profiles). Our compressor addresses all three—optimizing quality settings, stripping unnecessary metadata, and using efficient encoding.
Does JPG compression remove metadata and location data?
Yes, by default we strip all metadata including EXIF data, GPS coordinates, camera info, and timestamps. This is intentional for privacy and smaller file sizes. Location data is always removed. If you need to preserve specific metadata, keep your original file as a backup.
Can I compress JPG multiple times?
You can, but we don't recommend it. JPG is a lossy format—each compression cycle permanently removes some image data. Compressing the same image repeatedly degrades quality (called "generation loss"). For best results, always compress from your original source file, not from a previously compressed version.
How much can I reduce a JPG file size?
Typical results: 40-80% reduction for camera photos and unoptimized images. Already-compressed JPGs may see smaller gains (10-30%). A 5 MB iPhone photo often compresses to 1-2 MB. A 500 KB web image might become 300-400 KB. Results vary based on image content—photos with fine detail compress less than images with solid colors.
What quality setting does your JPG compressor use?
We use quality 85 (on a 0-100 scale) combined with state-of-the-art encoding algorithms including trellis quantization, optimized progressive scans, and tuned quantization tables. This delivers excellent visual quality while achieving significant file size reductions—the sweet spot for web and sharing use cases.
What are the file size and batch limits?
| Tier | Max File Size | Max Files/Batch | Parallel Jobs |
|---|---|---|---|
| Guest/Free | 25 MB | 50 files | 3 at once |
| Pro | 200 MB | 200 files | 6 at once |
| Business | 1 GB | 1000 files | 10 at once |
Note: Batch and parallel processing limits apply site-wide across all compressors.
How are credits calculated for compression?
Cost: 1 credit each
How it works:
- Files up to 25 MB: 1 credit (minimum)
- 26-50 MB: 2 credits
- 51-75 MB: 3 credits
- 76-100 MB: 4 credits
- Over 1000 MB: 40 credits (maximum cap)
Example: A 5 MB file = 1 credit. A 95 MB file = 4 credits.
Why per-megabyte? Larger files require more processing resources (memory, CPU, bandwidth, storage).
What are my daily and monthly credit limits?
Credit allocations vary by account tier:
| Tier | Credits | Reset |
|---|---|---|
| Guest | 50/day | Midnight UTC |
| Free | 50/day | Midnight UTC |
| Pro | 10,000/month | Billing cycle |
| Business | 30,000/month | Billing cycle |
Note: With 1 credit per file, Guest/Free users can compress 50 files per day. Pro users can compress 10,000 files per month.
