One app for six kinds of files

Each file type has its own tool. The four compression tools start on import and update when settings change. You start packing and extraction when you’re ready.

Image compression

Compress by quality, target size or reduction, and convert between JPEG, HEIC, WebP, AVIF and more.

Starts at 30% quality the moment you drop files in; switch to target size or reduction anytime

Target size is checked against the exported file’s real byte count, and misses are reported

Animations keep their frames and timing; exports drop location and camera metadata

PDF compression

Optimizes the file structure and recompresses embedded images, while text, bookmarks and links keep working.

Includes a 14-day free trial

U.S. prices in U.S. dollars. Confirm your local price in the App Store or Google Play before purchasing.

PubToo, PubToo Go and PubToo Lite are purchased separately. One Go purchase covers iPhone and iPad on the same Apple Account.

Subscriptions renew automatically. Cancel in the store you purchased from; that store handles payments and refunds.

The Mac and Go editions are currently not sold on the App Store in France.

Good to know

Are my files uploaded anywhere?

No. Compression, packing and extraction all happen on your device. PubToo has no account system and contains no advertising, analytics or tracking SDKs.

Will it change or overwrite my originals?

No. Results are exported as new files. Duplicate names are numbered automatically, and your folder structure is kept by default.

Will I be charged when the trial ends?

No. After the 14-day app trial, you choose whether to subscribe or buy lifetime access. Only a purchased subscription renews automatically; cancel it in the store you purchased from.

Does one purchase cover all three editions?

Mac, Go and Lite are purchased separately. One Go purchase covers iPhone and iPad on the same Apple Account. Apple and Google Play purchases do not transfer between stores.

Will it always hit my target size?

PubToo checks the exported file’s real byte count. If a target can’t be reached, it tells you, so you can raise the limit or allow resizing. It never hands you a file that’s over the limit.

Do I need an internet connection?

File processing happens on your device. Purchases, restores and subscription checks need the relevant store. Lite subscriptions also need periodic online verification.

Lighter files, less hassle
