Frequently Asked Questions

Is online image compression safe?

Yes. Your images are encrypted in transit (TLS 1.3) and at rest (AES-256). Files are processed on EU servers and automatically deleted after 1 hour. We don't view, share, or store your images beyond the processing window. No account required for basic usage.

Does image compression affect print quality?

For web/screen use: Our compression is optimized for display quality—differences are typically imperceptible. For professional printing: We recommend keeping original files for print production. Compressed images work well for proofs and drafts, but originals ensure maximum print quality.

What image formats can I compress?

We support the most common image formats: JPG/JPEG (photographs), PNG (graphics with transparency), WebP (modern web format), and AVIF (next-generation format). Drop any of these formats and we'll automatically detect and optimize them.

Which format gives the best compression?

For photographs: JPG offers the best balance of quality and compatibility. For graphics/screenshots: PNG preserves sharp edges and text. For transparency: PNG maintains alpha channels. Our universal compressor outputs JPG (for photos) or PNG (for images with transparency).

What's the difference between lossy and lossless compression?

Lossy (JPG, WebP, AVIF): Discards some image data for smaller files. Best for photos where tiny quality loss is acceptable. PNG: Our compressor uses palette-based optimization (similar to TinyPNG) which reduces colors for dramatic size savings while preserving sharp edges. Best for screenshots, logos, and graphics. For true lossless archival, keep your original files.

How do I compress multiple images at once?

Simply drop all your images at once! We support batch compression—up to 50 files simultaneously. Files are processed in parallel for maximum speed. Download individually or wait for all to complete and download as a ZIP.

How do I choose the right compression for my use case?

Email/messaging: Maximum compression acceptable—use JPG or WebP. Website images: Use WebP with JPG fallback for broad support. Social media: Platforms recompress anyway—moderate compression is fine. Archival: Keep original files for true lossless preservation. Modern web apps: AVIF for cutting-edge efficiency.

What are the file size and batch limits?

TierMax File SizeMax Files/BatchParallel Jobs
Guest/Free50 MB50 files3 at once
Pro1 GB1000 files6 at once

Note: Batch and parallel processing limits apply site-wide across all compressors.

How are credits calculated for compression?

Cost: 1 credit per 10 MB

How it works:

  • Files up to 10 MB: 1 credit
  • 11-20 MB: 2 credits
  • 21-30 MB: 3 credits
  • 31-40 MB: 4 credits

Example: A 5 MB file = 1 credit. A 95 MB file = 10 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:

TierCreditsReset
Guest100/dayMidnight UTC
Free100/dayMidnight UTC
Pro12,000/monthBilling cycle

Note: Credits are based on file size (1 credit per 10 MB). Guest/Free users have 100 credits per day. Pro users have 12,000 credits per month.
