App Name: Imgport

What it does: A fully offline batch image utility (no internet permission at all). Version 1.10.0 adds JPEG XL: it opens and views .jxl files, which most phones cannot display, and batch converts them to JPG, free.

Key Features:

- Built-in JXL viewer plus free JXL to JPG, PNG, or WebP conversion

- Saves JXL too, with a lossless mode that repacks JPGs about 15 to 30 percent smaller, reversibly (Pro)

- Photos never leave the device: no network permission, no accounts, no ads

Goal: Launch (v1.10.0 is out today)

Giveaway: The first 20 commenters get a free Pro unlock code by DM.

App Name: Imgport

What it does: Converts, resizes, compresses, watermarks, and strips metadata from photos in batches, fully on-device with no network permission. Version 1.4.0 adds a metadata viewer that shows everything hiding in a photo, and selective stripping that keeps only the fields you choose.

Key Features:

- See and strip hidden metadata: GPS, dates, camera, plus the copies most tools miss, like GPS inside XMP and embedded thumbnails. Strip selectively (Pro) or remove everything free, verified by read-back

- Watermark photos with your name or brand, with a live preview rendered by the same engine as the real run (Pro)

- 100% offline: batch HEIC to JPG, PNG, or WebP with your phone's own decoder, plus resize and compress to a target size. No ads, no accounts, no network permission

Goal: Promo

I last posted about three months ago, so this is a catch-up on what has shipped since then (video above).

App Name: DocuScanr

What it does: Scans documents with your phone camera and keeps every page encrypted on your device. No cloud, no account, nothing is ever uploaded.

Key Features:

- Automatic edge detection and perspective correction with a live-tracking viewfinder

- OCR text extraction: select, copy, and search inside your scans

- AES-256 encrypted library with PDF, JPEG, PNG, and encrypted ZIP export

Goal: Promo (3-month update digest)

Giveaway: None

New in the last 3 months:

- Tablet and landscape support: library sidebar, page thumbnail rail, redesigned landscape editors

- Scanning feels new: the live outline glides with your camera, and crop corners are accurate the moment a capture lands

- Export size presets (Small / Medium / Original) with a per-document size estimate

- Import password-protected PDFs and encrypted ZIPs (Pro), matching the locked exports

- OCR now shows everything it reads, even on faint print

- A much bigger free tier: multi-page scans, folders, imports, OCR, and JPEG/PNG export are all free, and the one-time Pro price was cut in half

Happy to answer any questions.

I'm the developer of Imgport, a batch image utility for Android. It processes photos entirely on-device: no accounts, no ads, and it holds no network permission, so nothing you process ever leaves your phone.

The clip shows a real batch: three photos resized to 1080 px, 3.5 MB saved, each file's before and after size on the receipt.

What it does:

- Convert iPhone HEIC photos to JPG, PNG, or WebP (uses your phone's own decoder, nothing bundled)

- Resize by longest edge, exact size, or percent, with a no-upscale rule

- Compress with a quality slider, or target a specific file size

- Strip hidden metadata like GPS, camera, and date, verified removed by read-back

- Batch everything: one bad file never fails the rest

Free to use, with an optional one-time Pro unlock for unlimited batch size, saved presets, one-pass workflows, batch rename, and keep-EXIF. No subscription.

I have a handful of promo codes for the Pro unlock. Comment below and I'll DM you one, first come first served.

DocuScanr encrypts all your documents on your phone using AES-256. No cloud, no accounts, no tracking. Once OCR's downloaded on first use, you can put your phone in airplane mode and use the entire app.

What it does:

- Auto edge detection + perspective correction (hybrid ML + OpenCV, all on-device)

- Multi-page scanning, batch capture, gallery/PDF import

- OCR with searchable text + plain-text reflow view

- PDF export (optional AES-256 password), JPEG/PNG/ZIP export, watermarks

- Annotations: ink, text, highlights, arrows, redaction, saved signatures

- Folders, tags

- Encrypted backups with a recovery key (so a lost phone doesn't mean lost docs)

- App lock with biometric unlock, screenshot prevention

- Optional crash reporting (off by default, scrubbed of PII when on)

Only things that touch the internet: buying Pro, optional crash reports, and the one-time OCR model download.
