Every imgkilo image tool in one place

imgkilo is a set of focused tools for the things people actually need to do with an image: make it smaller, change its format, resize it to fit, or turn a phone snap into a compliant ID photo. Every tool runs inside your browser, so your files are never uploaded to a server. Pick a tool below, or jump straight to a specific size or document.

Convert image formats

Change a file from one format to another while it stays on your device. Move to WebP for lighter pages, turn iPhone HEIC into universal JPG, or rasterise an SVG to a fixed pixel size.

Bulk & batch

Process a whole folder in one drop instead of one file at a time. Convert a mixed batch to a single format, compress hundreds of images at once, or resize every photo to the same size — all in your browser, returned as a ZIP.

Colour & transparency

Read the colour out of an image, or check what kind of file you really have. Eyedrop an exact pixel for its HEX, RGB and HSL, pull a whole palette of dominant colours, confirm whether a PNG is genuinely transparent, or find a file's true format from its bytes. Each runs in your browser, with nothing uploaded.

Redact & obscure

Hide what should not be seen before you share. Pixelate a whole image or just a face, blur a name or detail on a screenshot, or censor a number plate, all by dragging a box. Each runs in your browser, so the sensitive original is never uploaded.

Developer tools

Encode and decode images for code. Turn an image or SVG into a Base64 data URI for inlining in CSS and HTML, or paste a Base64 string back into a downloadable file. Everything is read and written in your browser, with nothing uploaded.

QR code generators

Build QR codes that scan reliably. Every tool surfaces the encoded payload so you know what scanners receive, with PNG / SVG / JPG export and centre-logo support backed by error correction H. URL, Wi-Fi, UPI, email, SMS, phone — one canonical tool per intent.

Create & sketch

Design a print-ready ID card, or turn a photo into a drawing aid with an adjustable grid. Both run in your browser — details and uploads stay on your device, and the output is ready to print straight onto card stock or paper.

Exam & government form photos

Application portals each demand the photo and signature at an exact pixel size, file size and format. These pages carry the published spec for a specific exam or recruitment board and resize your image to match, in your browser. Always confirm the numbers against the official notification.

Photo or signature rejected by a form?

If an upload bounced for being too large, too small, the wrong dimensions or the wrong format, find the exact message and fix it in your browser. Fix an image upload error.

Why these tools work without uploading

Most online image tools send your photo to a remote server, process it there, and send it back. imgkilo does the work in the browser tab you already have open, using the same Canvas and WebAssembly that power modern web apps. That is faster for you and means private photos, client assets and personal documents never touch a server you do not control.

Nothing leaves your device

All processing happens locally. You can verify it in the Network panel.

Faster than upload tools

No round trip to a server, so results are usually ready in under a second.

No login, no limits

Run one file or a hundred. No watermarks and no signup wall.

Modern formats included

WebP and HEIC are handled directly, not locked behind a paid plan.

Questions about the tools

Are all of these tools free?

Yes. Every tool on imgkilo is free with no account and no watermark. There is no paid tier that unlocks formats or removes limits.

Do my files get uploaded to a server?

No. Compression, conversion, resizing and the photo tools all run inside your browser using the Canvas API and WebAssembly. Your files never leave your device, which you can confirm in your browser's Network panel.

Which formats can I work with?

The tools handle JPG, PNG, WebP and SVG directly, and convert HEIC from iPhones into JPG. You can compress to an exact kilobyte size, resize by pixels, and build passport photos from any of these.

Is there a limit on how many images I can process?

There is no hard limit imposed by a server because nothing is uploaded. You can run a single file or a large batch; the only ceiling is your own device's memory.
