CaptureX · macOS 14+
Features & how to use them
Frame the content with smart selection, then make your annotations stand out in HDR. See real exported samples and the steps, formats and requirements for capture, recording and editing.
HDR for screenshots
Brighter emphasis. Details intact.
Give highlights, arrows and text up to 4× luminance gain. Mark what matters and save an HDR image, all in the same CaptureX editor.
- Capture, then enable HDR
- Annotate and adjust brightness
- Export with HDR preserved
An output sample made with fictional content, edited and natively encoded by CaptureX. Text in the sample is in English.
HDR and SDR versions of the same edit. Extra brightness requires an HDR-capable display and browser; otherwise, the two images may look similar.
- Edit & save
- macOS 15+. HDR annotations default to HEIC; PNG (16-bit PQ) and JPEG (gain map) also preserve HDR.
- Live HDR preview
- macOS 26+, an HDR display and WebGPU HDR support. Other environments show an SDR preview; macOS 15+ can still save HDR.
- Everyday copying
- Copy, Pin and drag-out use SDR. Export an HDR image to retain extra brightness. Your source stays unchanged.
Screenshots & recognition
| Feature | How to use it | Good to know |
|---|---|---|
| Smart selection: windows & regions | Press the shortcut, point at a window to snap to its edges, then click. Or drag a freeform region.⌃ ⇧ A | No second Enter confirmation. Adjust the boundary before your first edit. |
| Repeat last region | Press the shortcut to capture your last selected area again.⌃ ⇧ G | Reselect after a display or scaling change. |
| Smart selection: web & tables | Hold Shift, move to another element, then click or press Enter. No need to hold the mouse button. Select across rows, columns and merged cells. | Main panel → More → Enable element selection and grant Accessibility access. Needs page support. Frames the start and current elements; elements passed along the way are not added. Use freeform selection if recognition is unavailable. |
| Exact sizes | Click the width × height badge to enter dimensions. Choose px/pt in Settings. | Choose a common size or reuse recent sizes. |
| Scrolling screenshots | Select an area → Scrolling capture → scroll manually or start automatic scrolling → finish. | Watch the live preview. Capture pauses if matching is unreliable or the target is obscured. |
| Annotations & color | Choose arrows, text, shapes, mosaic or measurements directly on the toolbar. Find background and shadow beside Rotate. | Select and move annotations directly; undo, redo or press Delete to remove them. The original stays intact. |
| OCR & translation | Select OCR after capture. Choose a target language to translate, then copy either text. | Available before annotating or transforming the image. Translation needs macOS 15+ and installed system language packs. |
| QR codes | After capture, click a detected QR result to open its link. | QR recognition is local; links never open automatically. |
| HDR annotation editing | Turn on HDR in the toolbar, then add highlights, text, tags or arrows. Adjust brightness in the tool options, up to 4×. | Requires macOS 15+. Live preview needs macOS 26+ with WebGPU HDR display support; otherwise you see SDR. Actual brightness depends on display headroom. |
| Save with HDR intact | Choose HEIC, PNG or JPEG from Export. HDR annotations default to HEIC; PNG uses 16-bit PQ and JPEG uses Adaptive HDR. | All three HDR formats need macOS 15+; appearance depends on the receiving app. Whole-image copy, pin and drag-out use SDR. Failed saves keep your edits without silently discarding HDR. |
