Edit images, privately

Convert, compress, and clean up any image.

HEIC to JPG, background removal, resize, upscale, OCR — every operation runs on your device, with no per-image limit and no signup.

GhostImage edits and converts images entirely in your browser — nothing is uploaded. Convert between JPG, PNG, WebP, AVIF and HEIC, compress and resize, change DPI, remove the background with on-device AI, upscale, pull text out of an image (OCR), combine images into a PDF, scan a document with your camera, and strip metadata — free, no signup, no per-image limit. Even background removal and upscaling run locally with WebAssembly and on-device machine-learning models, so your photos never touch a server.

How it works

  1. 1

    Add your image

    Drag a photo in or click to browse. HEIC from an iPhone, PNG, JPG, WebP and AVIF all load directly.

  2. 2

    Convert, compress, or edit

    Choose an operation — convert format, compress, resize, change DPI, remove background, upscale, or OCR. Stack as many as you like.

  3. 3

    Download the result

    Save the finished image (or a PDF, if you combined several). It never left your device.

Questions, answered

How do I remove an image background for free?

Drop the image and choose Remove Background. An on-device AI model separates the subject from the background right in your browser — no upload, no per-image cap, and full resolution is free.

Can I convert HEIC to JPG without uploading?

Yes. Add an iPhone HEIC photo and choose Convert → JPG (or PNG/WebP). The decode and conversion happen locally, so the photo never leaves your device.

How do I change an image's DPI to 300 for printing?

Convert the image to JPEG first if needed, then use the Change DPI operation and enter 300. DPI is print metadata; GhostImage rewrites it without resampling your pixels.

Does compressing a PNG lose quality?

GhostImage uses smart compression that cuts file size substantially while keeping images visually lossless for most photos. You can preview the result before downloading.

Can I pull text out of a screenshot?

Yes. Use the Image → Text (OCR) operation to extract selectable text from a screenshot or photo, entirely in your browser.

Is there a limit on how many images I can process?

No. Because nothing is uploaded, there's no monthly quota or per-image cap — process as many as your device can handle.

Everything runs in your browser. Your files are never uploaded — for the single-file tools there's no upload endpoint to send them to.
