Everything is processed on your device, with no account and no uploads.\n\nImages\nPick from Photos or Files and compression starts as soon as they are imported. Work by quality, by percentage or toward an exact file size, resize along the way, and convert between JPEG, PNG, HEIC, WebP, AVIF and GIF. Compare before and after, then save to Photos or Files, or share the result with another app. Location and camera details are removed from exported images.\n\nPDF, video and audio\nPDFs can be optimized losslessly, balanced, or made as small as possible. Video is re-encoded as H.264 for compatibility or HEVC for smaller files, at the original resolution, 1080p or 720p. Audio exports as AAC, or stays lossless as ALAC or FLAC. Each can also work toward a target size.\n\nArchives\nCreate ZIP or 7z archives, with a password when you need one. 7z archives can also encrypt file names and be split into volumes. Protected archives open with their password, and each archive extracts into its own folder.\n\nDetails\n• Send files to PubToo Go from the share sheet in any app.\n• Add compression to your automations with Shortcuts.\n• Keep batches to return to later, or start fresh each time.\n• Originals are never modified and existing files are never overwritten.\n• No account, no ads, no tracking.\n\nTrial and purchase\nPubToo Go is free to download and includes a 14-day free trial. After that, choose a monthly, quarterly or yearly subscription, or a one-time lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed anytime in your App Store account settings. One purchase covers every compatible device signed in with the same Apple Account.\n\nTerms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/\nPrivacy Policy: https://www.pubtoo.com/en/privacy#mobile","facts":{"developer_id":1890581414,"developer_url":"https://www.pubtoo.com/en/#editions","first_released":"2026-09-16T07:00:00Z","support_url":"https://www.pubtoo.com/en/support#mobile","privacy_url":"https://www.pubtoo.com/en/privacy#mobile","website_url":"https://www.pubtoo.com/en/#editions","app_version":"1.1.12","release_notes":"• Improve image-processing memory use and stability\n• Improve HDR video colour and timing preservation","rating_current_version":null,"rating_count_current_version":0,"star_counts":[0,0,0,0,0],"genres":["Utilities"],"languages":["EN","FR","DE","JA","KO","PT","RU","ZH","ES","ZH"],"content_advisories":null,"device_families":["iphone","ipad"],"made_for_iphone_duo":true,"chart":null},"freshness":{"apple_read_at":"2026-11-13T11:18:12.870Z","catalog_read_at":"2026-11-06T12:47:13.011Z","reviews_checked_at":null,"summary_written_at":"2026-11-06T10:55:14.340Z","placed_at":"2026-11-06T11:55:13.326Z","scored_at":"2026-11-14T17:58:12.836Z"},"editorial":{"one_liner":"Compresses images, PDFs, video and audio, and creates or extracts ZIP and 7z archives, processed on your device.","what_is":"PubToo Go is a utility app that compresses images, PDFs, video and audio, and converts image formats.
