Layers, blend modes and masks
Build images the way you would in a desktop editor. Add as many layers as you need, drag them to reorder, rename, lock or hide them and set opacity per layer. Seventeen blend modes such as Multiply, Screen, Overlay and Soft light composite without touching the pixels below. Layer masks hide parts of a layer non-destructively: paint black to hide, white to reveal, then apply or delete the mask when you are done.
Brushes, shapes and text
The Brush has size, opacity, hardness, smoothing and pen pressure, and sits next to the Pencil, Airbrush, Eraser, Fill and a linear or radial Gradient. Rectangle with rounded corners, Ellipse, Polygon and Star draw as outline, solid or both, while Line and Arrow draw straight strokes with an adjustable width. The Text tool types straight onto the canvas in the final font, and every text layer stays editable, so a typo is never a reason to start over.
Retouching tools
Remove dust, blemishes and stray wires with Spot healing, which fills each stroke from its surroundings. The Healing brush and Clone stamp copy from a source you pick, Dodge / Burn lightens or darkens shadows, midtones or highlights, and the Blur, Sharpen and Smudge brushes soften, crisp up or push pixels exactly where you paint. There is no AI generative fill; these are manual tools that reward a steady hand.
Adjustments and filters
Fifteen sliders in the Adjust panel preview live: exposure, brightness, contrast, highlights, shadows, gamma, saturation, vibrance, temperature, tint, hue shift, clarity, softness, grain and vignette. Levels… and Curves… work per channel, and quick presets like Auto contrast or Punchy fix a flat photo in one click. The Filters panel adds 21 effects, from Grayscale and Vintage to Pencil sketch, each shown as a thumbnail of your own image.
Selections that keep edits in place
Rectangle select, Ellipse select, Lasso and Magic wand create selections — with a feathered edge if you set one — that you can add to, subtract from, intersect or invert. Everything respects the selection: brushes, fills, filters, adjustments and deleting all stop at its edge. That makes it easy to crop to an exact area, blur a single face, brighten only the foreground or make a background transparent without touching the subject.
Crop, resize and transform
Crop with ratio presets and rule-of-thirds guides, change the pixel dimensions in Image size…, or extend the canvas in Canvas size… with an anchor that decides where the picture sits. Rotate by 90° or 180°, flip, trim transparent edges automatically, or use the Transform tool to move, scale and rotate a layer by any angle. Documents can be up to 8000 × 8000 pixels, within the browser’s canvas limit (about 16.7 megapixels on iPhone and iPad).
Opens almost anything, exports what you need
Drop in PNG, JPEG, WebP, GIF, SVG, BMP, AVIF, iPhone HEIC photos or Photoshop PSD files with their layers, or paste a screenshot with Ctrl/⌘+V. Export as PNG, JPEG or — where the browser supports it — WebP with a quality slider, a scale slider and a live file-size estimate, save a layered PSD for another editor, or keep a .paint project that preserves every layer for later.
Private, offline and free
Paint Studio runs entirely in your browser tab. Images are never uploaded, there is no account, no ads and no watermark, and the code is open source under the MIT license. After the first visit it also works offline and can be installed as an app. Work in progress is autosaved in your browser and offered for restore the next time you open the editor.
Frequently asked questions
Are my images uploaded anywhere?
No. Paint Studio has no server that receives your files. Images are decoded and edited inside your own browser tab, and exports are created there too, which makes it suitable for personal photos, ID scans and screenshots with private information. The only file-related download is a HEIC decoder library, fetched in browsers that can’t open iPhone photos natively and then usually kept in the browser’s cache.
Is Paint Studio really free?
Yes. There is no trial, no paid tier, no sign-up and no watermark on exported images. The project is open source under the MIT license, so anyone can read the code, run their own copy or contribute on GitHub.
Does it work offline?
Yes, after your first visit. The editor is a progressive web app: it caches itself in the browser and can be installed to your desktop, dock or home screen. Work in progress is autosaved in the browser’s own storage, and the next time you open Paint Studio it offers to restore it. Very large documents are the exception: once all layers and layer masks together exceed about 192 megapixels (say, ten layers of a 24-megapixel photo), autosave is skipped, so save a .paint project instead.
Can I use it on a phone, tablet or Chromebook?
Yes. It runs in any modern browser and supports touch, pinch zoom and stylus input, including pen pressure where the browser reports it. A tablet with a pen is comfortable for drawing; on a phone it is best for quick crops, conversions, filters and adjustments.
Which file formats can I open and save?
You can open PNG, JPEG, WebP, GIF (first frame only), SVG, BMP, AVIF when your browser decodes it, HEIC/HEIF, 8-, 16- and 32-bit RGB or grayscale PSD files with their layers, plus .paint projects. You can export PNG, JPEG, WebP (in browsers that can encode it), a layered PSD, or a .paint project that keeps layers for later editing.
How large can an image be?
Up to 8000 × 8000 pixels on a computer, which covers photos from most phones and cameras. The browser also caps how large a canvas may be: Safari on iPhone and iPad stops at about 16.7 megapixels. Anything bigger is scaled down to fit when it opens, so you can still edit it, just at a lower resolution.
Does it have AI features like automatic background removal?
No. There is no generative fill and no automatic subject or background detection. Backgrounds are removed with the Magic wand, Eraser and layer masks, blemishes with the healing tools. That works well on plain backgrounds and small spots, and keeps every change predictable and local.
Which languages and themes are available?
The interface is available in English and Czech, with a dark and a light theme that follows your system setting until you pick one. Keyboard shortcuts work the same in both languages; press ? in the editor to see the full list of shortcuts.
