Image tools for every common workflow — resizing for a specific platform, compressing for email or web, cropping to an aspect ratio, converting between PNG / JPG / WebP, rotating, flipping, watermarking, colour-adjusting, and encoding as Base64. All of them run entirely in your browser using the Canvas API, which means your image data never leaves your device. No sign-up, no per-day limits, no watermarks added to the output. For photographers, designers, marketers, students, and anyone who occasionally needs a single image to be a slightly different image.
If you know the **exact pixel dimensions** you need, start with Image Resizer. If file size is the problem rather than dimensions, Image Compressor's split-view preview is the faster path. For **batch jobs** — a folder of product photos, a camera roll ready for web — skip straight to Bulk Resize. For purely cosmetic changes (brightness, saturation, a subtle blur), Color Adjuster and Blur / Sharpen are purpose-built. Most of the tools accept the same input formats and produce the same output formats, so you can chain them: resize → compress → watermark → download.
What file formats do these tools support?
PNG, JPG (JPEG), and WebP everywhere. Most tools also read GIF, BMP, and AVIF if your browser can decode them. Output is always PNG, JPG, or WebP depending on the tool.
What's the maximum image size I can process?
Most tools accept up to 50 MB per image. Very large photos (40+ megapixels) can briefly freeze the browser while Canvas decodes them — pre-shrink on mobile if you hit memory issues.
Does resizing or compressing lose quality?
Compression and downscaling are inherently lossy, but the tools use high-quality hermite/bicubic filtering and modern encoders (WebP + mozJPEG) so the result is as close to the original as the format allows. Upscaling past the source dimensions, by contrast, is always soft — use AI Upscaler for that (ships later).
Can I process many images at once?
Yes — Bulk Resize accepts any number of images and produces a zip with the resized set. File Renamer does the same for renaming workflows.
Are any of these tools uploading my files?
No. Every tool in this category runs entirely in your browser. Files you drop in are processed locally, never sent to a server, and discarded when you leave the page.
