Free Image Editing Tools — Organised by Job

Make it smaller

• Image Compressor — cut file size by adjusting quality, with a before/after comparison. Handles many images at once and can cap the maximum dimensions in the same step.
• Image Resizer — set an exact width and height, or scale by percentage, with proportions locked so nothing stretches.

For upload forms with a strict limit, resize first (about 1200–1600 pixels wide suits most forms), then compress. The guide to reducing image file size walks through it.

Change the format

• Image Converter — convert between JPG, PNG and WebP, in bulk.
• HEIC to JPG and HEIC to PNG — make iPhone photos open anywhere. Every other KitWren image tool also opens HEIC directly.
• Direct converters for common pairs: JPG to PNG, PNG to JPG, JPG to WebP, PNG to WebP, WebP to JPG, WebP to PNG.

Converting a JPG to PNG doesn’t create transparency or restore detail — it only changes the container. To get a transparent background, use the Background Remover.

Frame it

• Image Cropper — trim edges or crop to a fixed shape such as square or 16:9.
• Image Rotator — turn and flip photos that came out sideways.
• Social Media Image Resizer — presets for Instagram, Facebook, LinkedIn, X, YouTube and Pinterest; see the size cheat sheet.
• YouTube Thumbnail Resizer — crop to 1280 × 720.
• Profile Picture Maker — clean square crops for profile photos.

Clean it up

• Background Remover — removes a plain, evenly lit background and replaces it with transparency, white or a colour. Best for products, logos, signatures and portraits against a plain wall; see the background removal guide.
• Blur image and Pixelate image — hide faces, number plates and screen details.
• Watermark image — add your name or text before sharing your work.

Protect your privacy

Phone photos often record the date, the device and the exact GPS location where they were taken. Post a picture of your new house and that data may tell people where it is.

• Image Metadata Viewer — see what a photo reveals.
• EXIF Remover — save a clean copy with that data removed.

Official photos

The Passport Photo Maker crops a photo to the official size for Australia, the UK, the EU, the US, Canada, India, China and New Zealand, with a face guide to line up against and a 6×4 sheet to print. It doesn’t change the background, so take the photo against a plain white or light grey wall. The passport photo guide covers lighting and the most common reasons photos are rejected.

For designers and website owners

• Image Colour Picker — get the HEX and RGB codes of any colour in an image, such as your logo’s brand colours.
• Favicon Generator — create the small icons browsers show in tabs and bookmarks.

Three common workflows

Tips for better results

• Always work from the original. Every JPG save loses a little detail, so resize and compress a copy of the original rather than an image you’ve already edited several times.
• Crop before you compress. Removing unwanted areas first means the compressor spends its budget on the part that matters.
• Keep a master copy — a full-size PNG or the original photo — and export smaller versions from it for each use.

Why in the browser?

Personal photos, ID pictures and unreleased product shots are exactly the images you shouldn’t have to upload to a stranger’s server. Because the tools work on your device, there’s also no upload wait for large photos, and batch tools can process dozens of images while you watch.
