Optimize or resize
Use Compress Image to reduce file size. Use Resize Image to change dimensions while keeping proportions locked by default.
VaultIMG
Private image tools, right in your browser.
VaultIMG provides sixteen focused workflows for everyday image work, built so supported files stay on the user's device.
Work with images without uploading them
Image files can contain personal photographs, location details, and other information that does not need to pass through an online processing service. VaultIMG loads the application in the browser, then performs its core image workflows on the device that already holds the file. No account or server-side image store is required.
Choose the image task you need
Each tool opens a focused workspace for one job. These links go directly to the live tools, including format-specific options for JPG, PNG, WebP, SVG, and GIF where the workflow supports them.
- Compress ImageReduce file size with format-aware compression controls.
- Resize ImageChange image dimensions by width, height, or percentage.
- Crop ImageKeep the area you need with freeform and fixed-ratio cropping.
- Rotate ImageCorrect orientation with left, right, and 180-degree rotation.
- Flip ImageMirror an image horizontally or vertically.
- Convert ImageConvert supported images to PNG, JPG, or WebP.
- Overlay ImageRedact, blur, tint, mosaic, or layer content over an image.
- Image Color PickerSample exact color values from any point in an image.
- Watermark ImageAdd a configurable text watermark to an image.
- Edit MetadataReview, add, change, or remove supported metadata fields.
- Annotate ImageAdd text, shapes, arrows, highlights, and freehand notes.
- Remove BackgroundCreate and refine a transparent cutout locally.
- Favicon GeneratorCreate a downloadable favicon and app-icon package.
- Sharpen ImageImprove edge clarity with an adjustable live preview.
- Adjust Image ColorsTune brightness, contrast, saturation, and color tone.
- Image EffectsApply blur, sepia, vignette, posterize, and other effects.
Which image workflow should you use?
Crop or reorient
Crop Image keeps a selected area. Rotate Image corrects orientation, while Flip Image mirrors the content.
Convert or prepare
Convert Image moves between supported raster formats. The favicon, watermark, and background-removal tools prepare images for publishing and reuse.
Edit or inspect
Annotation, overlays, color adjustments, effects, sharpening, metadata editing, and color sampling help review or change an image without leaving the browser workspace.
Format-aware SVG, GIF, and WebP handling
SVG stays vector where it should
Supported SVG workflows edit markup, dimensions, viewBox, or vector transforms without rasterizing the file. Tools that need pixel output explain when PNG is the safer or more faithful result.
GIF animation is preserved where supported
Format-aware compression and editing workflows retain frames, timing, transparency, and looping. Static format conversion clearly uses the GIF's first frame instead.
WebP remains available across browsers
VaultIMG uses native browser WebP encoding when available and a local encoder fallback when it is not. The file still stays on the device throughout the operation.
Output choices stay explicit
When an operation cannot safely preserve a source format, the workspace states the output behavior before processing rather than silently changing what the downloaded file contains.
How local processing works
- The browser reads the image selected from the user's device. The source file is not submitted to a Mesanix image-processing endpoint.
- Image decoding, editing, format-aware processing, previews, and export run in browser memory using application code loaded on the device.
- The finished image, metadata file, or ZIP is handed to the browser's normal download, save, open, or share flow.
- Closing or reloading the workspace clears active in-memory file state; VaultIMG does not provide a server-side image history.
Practical limits of browser-based image work
Device resources matter
High-resolution images, large animated GIFs, and complex effects use the current device's CPU and memory. Some workflows apply clear megapixel limits to keep browser behavior predictable.
Formats behave differently
Raster images, vector SVGs, and animated GIFs do not share the same capabilities. VaultIMG adapts supported operations by format and explains any conversion or animation limitation in context.
Automatic cutouts may need refinement
Background removal runs locally and provides refinement controls, but detailed edges, low contrast, or complex scenes may still require manual adjustment before download.
Downloads vary by browser
Desktop browsers usually download generated files directly. Mobile browsers may open the result or use the device's Files or share interface instead.
Privacy model
- Core VaultIMG workflows do not send selected source images to Mesanix or third-party processing services.
- No account or profile is required to process an image.
- Mesanix does not store a server-side copy of source files or generated outputs.
- The browser still requests the site resources needed to run the application, but the selected image is not included in those requests.
Designed for dependable browser use
VaultIMG validates inputs, keeps processing work away from the main interface where browser support allows, and uses format-specific pipelines instead of treating every image as a static bitmap. The product is reviewed across desktop and mobile layouts, including touch interaction, previews, undo behavior, and generated downloads.
