🔒 Privacy & Security Notice (Transient Processing)

User privacy is important. Files uploaded to this website are processed only for the requested task and are not intended for permanent storage. The platform does not maintain copies of uploaded files, generated documents, images, or converted outputs after processing.

Our focus is on accessibility and convenience, ensuring you can work securely on any device with no account registration or software installation. Please avoid uploading highly confidential or classified documents unless permitted by statutory or agency policies.

Tip: Need to crop or format your processed images into official 2x2, 1x1, or passport photos with standard CSC name tags? Try our free client-side Picture Maker (ID & Passport Crop).

Presets:
Smallest File (Max Compression) Best Quality (Larger File)
Quality below 70% significantly reduces size, but text or sharp gradients may show compression artifacts.
80% typically achieves 60%–80% file size reduction with virtually no perceptible visual quality difference.
Transparent PNG/WebP images retain their transparent alpha backgrounds automatically.

Downscaling large camera/phone photos (e.g., from 4000px to 1920px) produces massive file size savings.

Images are compressed directly in your browser using HTML5 Canvas whenever possible, with zero server uploads. When server fallback processing is required, images are kept in isolated transient memory and purged automatically within 1 hour.

Format & Compression Standards

Comprehensive Image Conversion & Compression Guide

The Image Tools utility is an all-in-one graphic suite engineered for fast format transformation and file size reduction. Whether converting smartphone photos (JFIF, AVIF, WEBP) into universal JPEG / PNG formats for official portal uploads, creating ICO favicons, or compressing large files to satisfy strict agency file caps (such as the 1MB–2MB limits typical of CSC, PRC, and DFA portals), this utility delivers immediate results while protecting your privacy.

Featuring browser-side HTML5 hardware acceleration with seamless PHP GD/Imagick fallback, files are compressed locally without uploading data to remote servers whenever compatible.

How to Use This Tool

  1. Select Mode: Compress or Convert: Click Compress Image to reduce file sizes while maintaining format, or Convert Image to switch between extensions (JPEG, PNG, WebP, BMP, ICO, AVIF).
  2. Queue Your Image Files: Drag and drop one or more images into the upload drop zone, or click Browse Files from any computer or smartphone.
  3. Configure Compression or Format: In Compress mode, choose a quality level (80% Balanced is recommended for optimal savings with no visible quality loss). In Convert mode, select your target file extension.
  4. Scale Dimensions (Optional): Enable resizing to downscale high-megapixel camera photos to standard web dimensions (such as 1920px or 1200px) with locked aspect ratio.
  5. Execute & Inspect Savings: Click Compress Image or Convert Images. Compare the before-and-after visual preview and inspect the exact reduction in KB and percentage.
  6. Download Output Files: Download processed images individually, or save the complete batch at once with our consolidated ZIP download.

Guidelines & Practical Notes

Government Portal File Limits

Most licensure and civil service portals (PRC LERIS, CSC ORAOHRA) reject photos exceeding 1MB or 2MB. Compressing standard JPEGs at 80%–85% quality guarantees instant acceptance.

Preserving PNG Transparency

When optimizing logos, digital signatures, or graphics with transparent backgrounds, keep PNG format or choose WebP to preserve transparency.

Aspect Ratio Preservation

When resizing, check Lock Aspect Ratio or leave one dimension blank to ensure your image scales proportionally without stretching or distortion.

Zero Upload Browser Processing

Standard JPEG, WebP, and PNG compression executes directly inside your browser memory via HTML5 Canvas, ensuring complete confidentiality and zero wait time.

Frequently Asked Questions

Select the Compress Image tab, upload your photo, ensure the quality slider is set to 80% (Balanced), and click Compress. If the original photo was taken on a modern smartphone with 4000+ pixels, also toggle Scale Down Pixel Dimensions and enter 1920 in Max Width for even greater savings.

You can compress images up to 50MB directly inside your web browser with zero server uploads and complete privacy. Format conversions and server fallbacks support files up to 30MB, calibrated to perform smoothly without timeouts on shared hosting.

If an image has already been heavily compressed by a smartphone camera or messaging app, applying a high quality factor (like 90% or 95%) can occasionally yield a slightly larger file. ToolBayan alerts you immediately if this occurs so you can lower the quality slider to 70%–75% or keep your original file.

No. Both our browser compression engine and server processing preserve full 32-bit alpha transparency channels for PNG and WebP graphics.

Never. For standard formats, processing executes directly in your browser without uploading to our server. When server fallback is used, images are processed in transient memory and deleted immediately after download or destroyed within 1 hour.

Your privacy is paramount. Wherever supported by your browser, compression runs locally on your device with zero byte transfers to our server. When server processing is required for specialized legacy formats, images are kept in transient memory and automatically purged within 1 hour.

Usage Disclaimer

This utility provides lossy and lossless image transformation. While quality settings are carefully calibrated to prevent visible artifacts, users should maintain backups of their master original images before applying aggressive compression.
