Browser-local Image Workflow Tools
Choose the correct order for pixel cropping, dimension resizing, and PNG, JPEG, or WebP encoding, with explicit browser and privacy boundaries.

Published Browser-local Image Workflow Tools
Only tools that pass the current local content, functionality, interaction, and eligibility checks are listed.
Image Cropper
Crop a browser-readable JPG, PNG, WebP, or GIF static bitmap with an explicit X, Y, width, and height, then verify the returned output type.
Image Resizer
Resize a browser-readable JPG, PNG, WebP, or GIF bitmap to explicit pixel dimensions, with an aspect-ratio lock and verified PNG, JPEG, or WebP output.
Image Format Converter
Decode one browser-readable JPG, PNG, WebP, or GIF static bitmap and request a new PNG, JPEG, or WebP encoding without changing pixel dimensions.
Audience
Who uses these tools?
- People preparing an exact avatar, card, banner, document, or upload-form asset.
- Creators who need repeatable pixel coordinates and dimensions rather than a visual-only editor.
- Reviewers who must distinguish local handler behavior from page, browser, device, metadata, and sharing risks.
Decision rule: crop, resize, or convert
Crop removes pixels and changes composition. Resize resamples the chosen composition to a new grid. Convert keeps the grid dimensions and requests another encoding. If only one of those outcomes is needed, use one tool and avoid an unnecessary extra export.
Worked workflow: 4000 × 3000 photo to 1200 × 630 banner
The target ratio is 40:21. Using the full 4000-pixel width requires a 2100-pixel-high crop; a centered rectangle starts at X 0, Y 450, width 4000, height 2100. Export that composition, resize it to 1200 × 630, and choose the final format only after checking the receiving system. Recalculate when the subject needs an off-center crop.
Input and output checks at every boundary
Confirm source dimensions are each 1–16384 pixels, coordinates remain inside the source, ratio-derived sides remain within the same limit, and returned Blob MIME matches the selected output. After download, check composition, dimensions, MIME, transparency or background, visible artifacts, bytes, and destination acceptance.
Limit intermediate loss
Keep the untouched source. When a multi-tool workflow is unavoidable, prefer a suitable intermediate that does not discard a property you still need, and avoid repeatedly encoding JPEG or WebP. Each tool starts from the file selected in that tool; the tools do not share an in-memory pipeline.
Precise browser-local scope
The three AIGClub handlers use file selection, object URLs, browser decoding, Canvas, Blob, and download links without an application image-upload endpoint. The page can still load other network resources, and extensions, malware, shared profiles, synced folders, recipients, EXIF, ICC data, and animation remain outside this guarantee.

FAQ
About Browser-local Image Workflow Tools
Which operation should come first for a fixed aspect ratio and pixel size?
Choose the composition with a crop first, then resize that composition to the delivery pixels. Convert only when the destination encoding also needs to change.
Can I rely on the preview alone?
No. Open the downloaded file and verify its MIME, dimensions, edges, transparency or background, visual quality, and behavior in the actual recipient.
Do these tools form a lossless pipeline?
No. Canvas decoding and encoding can alter pixels or properties, and JPEG/WebP can be lossy. Keep the original and minimize exports.
Does browser-local processing prove the page sends no requests?
No. It describes the image handlers, which have no application upload call; it is not a whole-page, extension, device, or anonymity claim.
