## What is かんたん画像圧縮?

An image compression and resizing app that quickly shrinks your photo file sizes. When you hit a social media upload limit or a marketplace app's file size cap, compress and send in seconds.

■ Hit a target file size automatically
• Just enter a target size like "500KB" and quality adjusts automatically
• Supports JPEG, PNG, WebP, and AVIF with a high-quality conversion engine

■ Resize at the same time
• Choose by long-edge length, width/height, percentage, or social-media size presets
• Keeps the aspect ratio (shrinks only — never upscales)

■ Batch processing
• Convert and save multiple photos at once
• A before/after slider to compare quality

■ Built with privacy in mind
• Everything is processed on your device — no internet connection needed
• EXIF and location data are automatically stripped on save

■ AI support (Premium)
• Ask the AI when you're unsure about settings
• Just say "keep it under 800KB" and the AI handles the settings and conversion for you

■ Premium plan
• Unlimited AI support
• Ads removed

Good for: any time you need to shrink a photo fast — social media posts, marketplace listings, email attachments, blog uploads, and more.
