PixKit

Compress photos, convert HEIC to JPG and turn images into a PDF, all on your own phone. Eight photo tools, no photo permission, nothing uploaded, and it works with the network switched off. COMPRESS PHOTOS Shrink large photos down to a size that uploads quickly. Choose a quality level or set a longest edge, and PixKit shows the real before-and-after figure, so you can see exactly how much smaller the file became. CONVERT IMAGE FORMATS Convert between JPEG, PNG and WebP with a quality slider. Popular conversions include HEIC to JPG, PNG to JPG, WebP to JPG, HEIC to PNG, JPG to PNG and JPG to WebP. HEIC photos from your camera are decoded by Android itself, so no extra decoding library is bundled and the app stays small. IMAGES TO PDF Turn photos into a PDF. Select several images, pick A4, Letter or a page that matches the photo, choose portrait or landscape, and get one clean PDF ready to send. Photo to PDF, JPG to PDF, PNG to PDF, WebP to PDF. COLLAGE MAKER Arrange up to 50 photos in 2, 3 or 4 columns, on a square, 4:5, 9:16 or 16:9 canvas, with adjustable spacing, rounded corners and a background colour of your choice. TEXT WATERMARK Stamp text onto a photo, place it anywhere on a 3x3 grid or repeat it across the whole image, then control size, opacity, angle, colour and shadow. RESIZE IN BATCH Resize one photo or many at once by longest edge, by percentage or to an exact size, keeping the aspect ratio if you want. CROP AND ROTATE Drag the corner handles with guiding thirds lines, rotate in 90 degree steps, flip horizontally or vertically, and snap to common aspect ratios. IMAGE INFO AND EXIF Check dimensions, file size, format, MIME type and colour space, plus EXIF data including camera model, lens, ISO, exposure, aperture, focal length and any location tag stored in the file. YOUR PHOTOS NEVER LEAVE YOUR DEVICE PixKit asks for no photo, camera, media or storage permission. Images reach the app only through the system photo picker, the same dialog Android uses everywhere, so PixKit can see just the pictures you hand it and never your whole library. Everything is processed in memory on your device. There is no account, no sign-in and no cloud service: nothing is uploaded and no copy is kept. IT WORKS WITH THE NETWORK SWITCHED OFF Put your phone in aeroplane mode and every tool still works. Compress, convert, create a PDF, build a collage, add a watermark, resize, crop and rotate, all offline. The app declares the internet permission for one reason only, which is loading the optional reward video. FREE, WITH AN HONEST LIMIT PixKit is free and supported by a single optional rewarded video. It never appears on its own and never interrupts your work. Use the free runs included each day, and if you would like more, you can choose to watch a short video. If no video is available, the app keeps working. No banners, no full-screen interstitials, no pop-ups. IN DETAIL Results are saved to Pictures/PixKit for images and Downloads/PixKit for PDFs, or to a folder you pick yourself. Your originals are never modified, because every tool writes a new file. Available in English, Chinese, Japanese and Russian, with light and dark themes, in an install of under 8 MB. Questions, problems or a tool you would like to see?
