PixelVision Lab
Resize to exact pixels
Set a width, a height or a percentage and keep the aspect ratio locked. Resampling is smooth, so a downscaled photo stays clean instead of turning blocky.

Image tools for the everyday.
Image tools for the everyday.
Photos and scans when they matter.
PixelVision Lab builds focused Android apps for image work, document photos and paper scanning. Edit a batch, prepare an ID or passport photo, or turn pages into a private PDF, all on your device.
Now on Google Play
Three focused apps. All on-device.
Choose the everyday image toolkit, a print-focused document photo workflow or a private paper scanner. None needs an account, and your files stay on your phone.
All the everyday image chores, in one quiet app.
Resize, compress, convert, crop, rotate, filter and batch-process images on the device. Built for photographers, sellers and anyone who handles a folder of photos a week.
A controlled path from portrait to print.
Create ID, passport and visa photos with face alignment, background replacement, exact dimensions and print layouts for 10×15 cm or A4 paper.
Paper in. A clean local PDF out.
Capture or import document pages, correct the edges and perspective, improve readability, then export a multipage PDF or individual JPEG and PNG pages.
What it does
One screen per job.
Pick a file, pick a tool, change the one thing you came for, export. No layers, no project files, no menus you will never open.
Compress without mush
Dial in the quality you actually need, in JPEG or WebP. A live size estimate shows the resulting file size before you export, so you never guess.
Convert between formats
JPEG, PNG and WebP, with a quality control wherever the target format is lossy. PNG stays lossless, so the quality slider steps out of the way.
Crop with a grid
Drag a freeform selection with eight handles, or snap to 1:1, 4:3 and 16:9. A rule-of-thirds overlay is always on.
Rotate & flip
Quarter turns and horizontal or vertical mirrors for the quick fixes, plus a 0–360° angle slider for straightening a scanned page or a tilted horizon.
Twelve filters
Blur, sharpen, denoise, edges, threshold, morphology, auto-enhance, brightness and contrast, HSV, grayscale, colour map and invert — each with its own controls.
File info
Exact dimensions, megapixels, aspect ratio, orientation, format and file size — read from the original file, which is never modified.
Histogram
See the tonal distribution as luma or as separate red, green and blue channels before you touch a brightness or contrast control.
Batch with one recipe
Pick a filter, an output format and a quality level, then run it over a folder of photos. A file that fails is skipped and reported — the rest of the queue keeps going.
Your files stay yours
Originals are never overwritten. Saves land in an Image Toolbox album in your gallery, where any other app can find them — and nothing is uploaded anywhere.
Inside the app
Straight from Image Toolbox.
Real screens from the Play Store listing — home, resize, compress, convert, crop, rotate, filters and batch.
Scroll horizontally for all eight screens.
How we build
Three rules we do not break.
The app catalog is small on purpose. Each release has to earn its place on your home screen.
Local first
Every operation runs on the device. There is no upload step, no waiting on a queue, and no server holding a copy of your photos or scanned pages.
Clear choices
Image Toolbox and ID Photo Maker are free, with optional one-time upgrades. DocScan is free to use. None of the three uses a subscription.
Small and honest
A lean app, clear permissions and a privacy policy in plain language. Image Toolbox uses a fixed banner; ID Photo Maker and DocScan have no ads. DocScan has no Internet permission.
Free on Google Play
Pick the app that fits the job.
Process a folder of images, prepare a document photo or scan paper into a PDF. All three apps install from Google Play, with no account or trial timer.
