Canva is the default recommendation for budget book cover design, and it earns that position. But there is a category of cover design where Canva's template-forward approach is the wrong tool: atmospheric composite covers that require layered photo manipulation, color grading, and precise masking. Thriller covers with figures emerging from shadows, fantasy covers with composite landscape elements, horror covers that blend multiple photographs into a single atmospheric scene — these are not what Canva is built for. Photopea is.
Photopea is a free, browser-based image editor that runs inside your web browser without installation. Its interface is nearly identical to Photoshop, down to the keyboard shortcuts and layer panel behavior. It opens PSD files, supports adjustment layers, layer masks, blending modes, smart objects, and all the core tools that make Photoshop the professional standard for composite image editing. For authors who want Photoshop-level control without a Creative Cloud subscription, Photopea is the most capable free option available.
Setting Up a Book Cover Document in Photopea
Open Photopea at photopea.com in any modern browser. To start a new document, go to File, then New. For a standard Kindle ebook cover, set the width to 1600 pixels and the height to 2560 pixels. Set the resolution to 300 DPI and the color mode to RGB. Name the document and click Create. This gives you the standard 1:1.6 portrait ratio at resolution suitable for digital publishing — sharper than most readers will ever display it, but correct for any platform's upscaling.
For a KDP print cover where you need a full wrap, you will need to calculate your canvas dimensions first based on your spine width and trim size, then set up the document to those custom pixel dimensions. Photopea handles custom canvas sizes without any limitations, unlike Canva's fixed-format approach.
Once your document is open, the workspace looks like Photoshop: tools on the left, layers panel on the right, properties at the top. If you have used Photoshop before, you are already oriented. If this is your first time in either interface, the next sections walk through the specific workflow for cover construction.
Building a Layered Cover: The Core Workflow
Open your background image by going to File, then Open and Place. This places the image as a new layer above your blank canvas. Press Control plus T (or Command plus T on Mac) to enter Free Transform mode. Drag the corner handles to scale the image to fill the canvas. Hold Shift while dragging to constrain proportions. Press Enter to confirm the transform. This is your base layer.
To add atmospheric depth — darker edges, vignette, or a color cast — add an adjustment layer. Click the half-circle icon at the bottom of the layers panel and choose Curves. In the Curves dialog, drag the center of the line downward to darken the image overall, or drag the ends to create a vintage or dramatic tone. The adjustment layer applies non-destructively, meaning your original image is unchanged. You can hide or modify the adjustment at any time without starting over.
Layer masks are how you blend multiple images together. If you have a figure from one photograph that you want to composite against a landscape from another, place both images on separate layers. With the top layer selected, click the mask icon at the bottom of the layers panel (the rectangle with a circle inside). This adds a white mask to the layer. Paint on the mask with a black brush to hide parts of the top layer, revealing the layer below. The brush hardness controls how soft the edge is — a hard brush for crisp edges, a soft brush for seamless blends. Paint with white to reveal hidden areas again. Masks are never permanent until you flatten the document.
Typography in Photopea
Select the Type tool from the toolbar (the T icon) or press T. Click on the canvas to place a text cursor, or click and drag to create a text box. Type your title text. The character options at the top of the screen control font family, size, weight, and color. For a cover title, start at a minimum of 150 pixels for a 1600 x 2560 canvas — this is the rough equivalent of what will read clearly at thumbnail size — and increase from there based on the length of your title.
Photopea does not have its own font library the way Canva does, but it reads fonts installed on your operating system and, critically, allows you to load web fonts through the More Fonts option in the font dropdown. This gives access to the full Google Fonts library directly within Photopea — thousands of typefaces available without installation or cost. For a book cover, navigate to Google Fonts, find the typeface you want, note its name, then type it into the Photopea font search. It loads directly from Google's servers.
Apply layer styles to text for professional polish. Double-click on the text layer in the layers panel to open the Layer Style dialog. Drop Shadow adds a slight shadow behind the text, which can lift light text off a light background enough to make it readable without changing the color. Stroke adds an outline around each letter. Outer Glow creates a soft halo that improves readability on busy backgrounds. These are Photoshop-standard features that Photopea implements completely.
Color Grading for Atmosphere
The visual tone that distinguishes a professionally designed cover from an amateur one is often a matter of color grading — aligning the color palette across all elements so they feel like they belong in the same world. A blue-tinted stock photo background with a warm orange figure on top will always look composited. Matching the overall color temperature is what makes a composite feel seamless.
In Photopea, use Hue/Saturation adjustment layers set to clip to specific layers (hold Alt while clicking between layers in the panel to create a clipping mask) to shift the color balance of individual elements. A slight desaturation of the background and a matching slight desaturation of the foreground element will bring them into the same visual register. Then add a Color Balance or Selective Color adjustment layer at the top of the stack affecting all layers, pushing the whole image toward the genre's expected color palette — cooler blues for thriller, warmer ambers for romance, deep teals and purples for fantasy.
Exporting Your Cover from Photopea
When your design is complete, save the working file first. Go to File, then Save as PSD to keep the layered, editable version in Photoshop format. This allows you to return and make changes later without starting from scratch. Store this PSD file — it is your source file.
For the export that you will upload to KDP or any ebook platform, go to File, then Export As, then JPEG. Set the quality slider to 90 or higher. Click Save and download the file. For print covers that require PDF, go to File, then Export As, then PDF. Ensure the resolution setting matches your canvas DPI (300) and the color profile is set to sRGB.
Photopea is ad-supported in its free tier, which means you will see ads along the right side and occasional prompts to upgrade. The free tier has no functional limitations relevant to cover design — all tools, all export formats, all layer types are fully available. The paid tier removes ads and adds a few workflow features for power users, but is completely optional for authors designing their own covers.
