What Photo Editor helps you do
Adjust brightness, contrast, saturation, grayscale and blur, rotate or flip the frame, and add a caption, all on one photo. It is a quick touch-up tool for photos that need minor corrections rather than a full desktop editor. The preview is capped for speed, but the download is rendered at the source resolution.
Editing happens in your browser. The photo is never uploaded to Haivix.
How it works
These tools decode the image in your browser, draw it onto a canvas, apply the change, and encode a new file. Nothing is uploaded, so the result depends on the browser's own decoders and encoders rather than a server library. Re-encoding always creates a new file: metadata such as EXIF, GPS and color profiles is generally dropped, and JPEG or WebP output loses a little quality on every save. Canvas work is capped at roughly 36 megapixels, so very large images may be refused rather than processed slowly. Browsers normally apply EXIF orientation when decoding, so a phone photo usually appears upright before any rotation is applied.
How to use Photo Editor
- Open a photo and adjust brightness, contrast, saturation and blur.
- Rotate or flip it and add a caption if you want one.
- Compare the preview with the original before exporting.
- Download the edited PNG.
When to use it
- Brighten or correct a dull photo before posting it.
- Add a caption or label directly onto an image.
- Make a quick grayscale or blurred-backdrop version.
- Straighten a phone photo with a flip or quarter turn.
- Prepare a simple social image without a design tool.
- Add a short title to a photo for a slide.
When not to use it
- Do not use it for layers, masks or fine retouching.
- Do not expect the preview to show every pixel of a very large photo.
- Do not save over the original; the export is a new PNG.
Example
Raising brightness and contrast slightly and adding a lower caption turns a flat photo into a shareable version. The preview is limited to about 920 pixels wide, so fine noise is easier to judge in the exported file. Caption text is drawn over the image and cannot be edited after export.
What you can do with Photo Editor
- Adjust brightness, contrast and saturation.
- Apply grayscale and blur.
- Rotate by 90 or 180 degrees.
- Flip horizontally or vertically.
- Add a caption with size, color and position.
- Export a PNG at the source resolution.
Example: pick the format for the job, then check the result
Keep the original. Every tool downloads a new file, and repeated conversion between lossy formats compounds artifacts.
Choose the format by purpose: PNG for sharp edges, text and transparency; JPEG for photographs; WebP when file size matters on the web.
Check transparency before converting to JPEG. Alpha is flattened onto a background color, and the choice is permanent in the output.
Look at the output at 100 percent. Smoothing, sharpening and watermark placement are easier to judge at full size than in a small preview.
For a batch, check the ZIP contents and file count. A single failed image is reported separately and does not stop the rest.
Note the output dimensions and file size. A larger pixel count does not always mean a better result, and a large PNG can be slower to load than a smaller JPEG.
What to know before you start
- Edits are non-destructive within the session but are baked in on export, so keep the original.
- It is a lightweight editor and does not offer layers or advanced retouching.
- The preview is downscaled, so it is not a pixel-accurate proof.
- Export is PNG only, with no JPEG quality option.
Common mistakes
- Judging sharpness from the scaled preview.
- Forgetting that the export is always PNG and may be large.
- Adding a caption that overlaps an important part of the photo.
- Resetting the edits after exporting and losing the look.
Troubleshooting
If the preview looks soft, the editor downscales for display; check the exported file.
If the caption is off-screen, choose a different position or reduce the size.
If the image is slow to update, the browser is re-rendering a large canvas.
If the download is disabled, no photo is loaded.
Related standards and documentation
- PNG is specified by the W3C and supports lossless compression and alpha.
- JPEG is standardized as ISO/IEC 10918 and is lossy.
- WebP is a Google format with both lossy and lossless modes.
- sRGB (IEC 61966-2-1) is the usual color space for web images.
- EXIF (CIPA DC-008) stores camera settings and can include GPS coordinates.
- ICC profiles describe a device's color gamut, and most canvas exports do not preserve them.
- Keep the source file.
- Match the format to the use.
- Check alpha and size.
- Inspect the export.
