All Image Tools
Ten tools. Zero uploads. Everything in your browser.
Every tool on this page runs entirely in your browser using modern JavaScript and the HTML5 Canvas API. Your files never leave your device — no upload, no server, no storage. The CPU that processes your image is the one in your own machine.
This matters more than it sounds. Traditional image tools upload your file to a server, process it there, and hand back a download link. That works, but it means your photos travel across the internet, sit on a server you do not control, are limited by your upload speed, and require a working connection for every single operation. Browser-based tools skip all of it.
Resize — for logos and social media
The Logo Resizer produces a complete logo package from a single upload: 64, 128, 256, 512, and 1024 px square icons, plus wide lockups for wordmarks. Enable the optional secondary upload for a horizontal logo and the export includes both versions at every size. Choose individual downloads or a single ZIP.
The Social Media Resizer generates every social platform size from one photo: Facebook post and cover, Instagram post and story, X post and header, LinkedIn post and banner, YouTube thumbnail, Pinterest pin, and TikTok video. Same workflow — pick the sizes you need, download as a batch.
Both resizers use a high-quality downscaling algorithm that halves the image repeatedly rather than resampling in one step. The difference shows at small sizes: a 4000 px photo shrunk directly to 64 px goes mushy. The same photo downscaled through intermediate steps stays sharp. That is why ImageCroply favicons and social thumbnails look better than what most tools produce.
Convert — between formats
The Format Converter handles JPG, PNG, WebP, and AVIF in both directions. Adjustable quality for lossy formats (JPG, WebP, AVIF), transparency-aware conversion to JPG (you pick the fill color for transparent regions), and a live preview of file size before you commit to a download.
Practical use: converting a Figma export from PNG to WebP typically cuts file size by 60 to 80 percent with no visible quality loss. Same for converting DSLR JPGs to WebP before uploading to a CMS.
Compress — smaller files, same look
The Image Compressor is for cases where the file size matters more than pixel-perfect preservation. Set a target quality between 20 and 100 and watch the compressed preview and file-size badge update in real time. Optionally resize to a maximum width in the same pass — a 4000 px photo at quality 75 will often compress to under 200 KB, versus the 3 to 5 MB original.
Web performance is measurable. Google PageSpeed and Core Web Vitals both penalize large images, and an image that loads 500 ms faster on a 4G connection can lift conversion rates by 1 to 3 percentage points on e-commerce sites. Compressing before upload is free performance.
Optimize — metadata cleanup and lossless re-encode
The Image Optimizer strips metadata and re-encodes cleanly. EXIF data from phone photos typically includes GPS coordinates, camera make and model, timestamps, and orientation — often 100 to 500 bytes per file, sometimes more. Stripping it protects your privacy and slightly shrinks the file. For images already optimized, the tool honestly reports when the output is larger than the input and offers a "keep original" button.
Placeholder images — for mockups and development
The Placeholder Image Generator creates clean placeholder images for wireframes, prototypes, and design mockups. Set the dimensions, background color, and text label, and download a PNG. No upload required — the image is drawn entirely in your browser.
Which tool should I use?
| Goal | Tool | Why |
|---|---|---|
| Logo icon at multiple sizes | Logo Resizer | Preset sizes match the standards (favicon-adjacent, app icons, social profiles). |
| One photo → many social sizes | Social Media Resizer | Every platform size in one batch, ZIP export. |
| Convert PNG to WebP | Format Converter | Adjustable quality, size preview before download. |
| Reduce file size for a website | Image Compressor | Live quality slider, size comparison, optional resize. |
| Remove GPS from a phone photo | Image Optimizer | Scans for EXIF / XMP / ICC and strips them cleanly. |
| Placeholder for a mockup | Placeholder Generator | No upload needed — pure canvas. |
Why browser-based beats server-based
Three concrete advantages: speed, because there is no network round trip; privacy, because your file never touches a server; and cost, because we do not pay for bandwidth or storage. The last one is why every tool here is genuinely free with no watermark, no premium tier, and no account required.
Chrome, Safari, Firefox, and Edge all support the Canvas API natively, so quality is identical across browsers. Mobile Safari and Chrome on Android work the same way. If a browser supports the output format you pick (e.g. AVIF encoding is Chrome-only at the time of this writing), the tool falls back gracefully and tells you so.
Start with any tool below — the workflow is the same across all of them.
Frequently asked questions
Are these tools really free?
Yes. No signup, no payment, no watermark, no hidden premium tier. Every tool on this page is free to use for personal and commercial projects.
Are my images uploaded to a server?
No. Every tool runs entirely in your browser using the HTML5 Canvas API. Your images never leave your device — nothing is uploaded, stored, logged, or shared.
What file formats are supported?
JPG, PNG, and WebP across all tools. AVIF is supported as input everywhere and as output in browsers that can encode it (currently Chrome and Edge). SVG input is supported by the Logo Resizer and the (coming) SVG Optimizer.
Is there a file size limit?
Each file must be under 2 MB. This is chosen to keep processing fast on mobile devices, not a technical limit of the browser — you can work with 8000px images comfortably.
Do these tools work on mobile?
Yes. All tools work on modern iOS Safari and Android Chrome. Touch drag-and-drop works on supported devices, or you can use the file picker.
What happens to my files after I close the tab?
Nothing is stored anywhere — no server, no cache, no cookie. The moment you close the tab, the in-memory copy of your image is gone.
