かんたん画像圧縮 -写真リサイズ・軽量化-

Shrink photo file size in one tap. Set a target size and let it adjust — supports JPEG/PNG/WebP/AVIF.

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.
