Which ImageDoctor tool should you use? A guide to all of them

ImageDoctor has grown to more than thirty tools, which is genuinely too many to skim. Most people only ever need three or four — the problem is finding out which three or four. This article is the map.

Three ways to edit an image, compared

Before the tool list, the choice that sits above it: where the work actually happens.

Browser-based tools sit in a genuinely useful middle: no install, no upload, no account, and fast enough for everyday work. The one real limit is memory — a 40-megapixel RAW conversion on an old phone will struggle where a desktop application would not. ImageDoctor warns you before opening something large enough to be a problem.

The everyday image tools

These five cover most of what anyone needs.

• [Image Compressor](/tools/compress) — make a file smaller, by quality or to an exact size in KB or MB, with a side-by-side quality check.
• [Image Resizer](/tools/resize) — change dimensions: exact size, a percentage, or a bounding box that caps without enlarging.
• [Image Cropper](/tools/crop) — crop freely or to a fixed ratio, rotate, straighten and flip.
• [Image Converter](/tools/convert) — move between JPG, PNG, WebP and AVIF, with control over transparency and background colour.
• [Image Editor](/tools/editor) — brightness, contrast and colour, plus drawing, annotation and text on a layered canvas.

Two shortcuts sit on top of them. Image Optimizer does resize, format and metadata in one pass with web-ready defaults — the right choice when the goal is simply "prepare these for my site". Batch Image Tools applies resize, compression, conversion and watermarking across dozens of images in one go and returns a ZIP.

Tools for a specific job

• [Watermark Tool](/tools/watermark) — stamp text or a logo, with position, rotation, opacity and tiled coverage.
• [Blur & Pixelate](/tools/blur) — paint blur or pixelation over faces, addresses and account numbers before sharing a screenshot.
• [Image to PDF](/tools/image-to-pdf) — combine images into one PDF with page size, orientation and margins. Up to 200 images.
• [PDF to Image](/tools/pdf-to-image) — render PDF pages to PNG or JPG at a chosen DPI.
• [Social Media Image Resizer](/tools/social-resizer) — current post, cover, story and profile sizes for the major platforms.
• [Passport Photo Maker](/tools/passport-photo) — exact millimetre sizes and DPI, tiled onto printable paper.
• [ID Photo Maker](/tools/id-photo) — custom size, background and copy count for badges and permits.
• [Profile Picture Maker](/tools/profile-picture) — circle, square or rounded avatars with padding, borders and backgrounds.
• [Favicon Generator](/tools/favicon) — favicon.ico plus every PNG size a site needs, with the HTML snippet and manifest.
• [Screenshot Tool](/tools/screenshot) — paste a screenshot and crop, annotate, arrow, highlight and blur it.
• [Brand Poster Maker](/tools/brand-poster) — templates that re-flow between formats, driven by a reusable brand kit.

QR codes and barcodes

The QR & Barcode Studio is a set of tools that hand off to each other: generate, style, brand, batch, label, print.

• [QR Code Generator](/tools/qr-code) — links, Wi-Fi, contacts and payments, with custom colours, shapes, logos and a scan check.
• [Barcode Generator](/tools/barcode) — EAN-13, UPC-A, Code 128, Code 39, ITF-14 and more, with check-digit validation.
• [QR + Barcode Label](/tools/qr-barcode) — both codes on one card with product name, SKU and price.
• [Bulk QR Codes](/tools/bulk-qr) and [Bulk Barcodes](/tools/bulk-barcode) — hundreds of codes from a spreadsheet, validated row by row.
• [QR Poster](/tools/qr-poster) and [Barcode Poster](/tools/barcode-poster) — signs, price tags and table cards.
• [Label Maker](/tools/labels) and [Print Sheets](/tools/print-sheets) — data-driven label designs, laid out with crop marks and bleed.

There is a full walkthrough in QR codes and barcodes that actually scan.

Developer and inspection tools

• [Image to Base64](/tools/base64) — encode a file as a data URI, with ready-made HTML, CSS and JSX snippets.
• [Base64 to Image](/tools/base64-to-image) — paste a string, preview it, download or convert it.
• [Image Metadata Viewer](/tools/metadata) — read EXIF, camera, GPS and colour data straight from the file.
• [Image Metadata Remover](/tools/metadata-remover) — strip it, and compare what was removed.
• [Color Picker](/tools/color-picker) — sample any pixel for HEX, RGB, HSL and RGBA, and build a palette.
• [Image Analyzer](/tools/analyze) — dimensions, weight, transparency and colour, with practical suggestions.
• [Image URL Processor](/tools/image-url) — load an image by URL, then treat it like any local file.

Background removal lives in a separate free tool, because it is built on a differently licensed model:

Two things worth knowing about all of them

Nothing is uploaded. Every tool decodes and processes the file inside your browser. There is no account, no email collection, and no server that receives your images.

Your settings stay with you. Presets, recent codes and saved projects are kept in your own browser's storage so you can pick up where you left off. Clearing your site data removes them; they were never anywhere else.
