Are my images uploaded anywhere?

No. Your files are decoded, edited and re-encoded by JavaScript running in your own browser. Nothing is transmitted, nothing is stored on a server, and closing the tab discards everything.

How does the site stay free if there is no server?

Advertising. Every conversion and every download is preceded by a short sponsored break. That is the whole business model — which is also why the tool stays completely free for you.

What is the difference between quality and file size?

Quality is the knob; file size is the result. Lowering quality produces a smaller file, but there is a floor below which the picture visibly degrades. If you tell the converter a target size instead, it searches for the highest quality that still fits your budget.

Which formats can I convert between?

JPG, PNG, WebP, AVIF, BMP and GIF can all be both read and written. HEIC, TIFF, SVG and ICO can be read where your browser supports them. The output list only shows formats your browser can actually encode.

Why does my PNG become larger when I convert it to JPG?

It should not — that would mean something is wrong. Converting in the other direction (JPG to PNG) routinely makes files much larger, because PNG stores pixels losslessly while JPG discards detail.

Can I convert several images at once?

Yes, up to twenty files per batch with a 40 MB ceiling each. They are processed two at a time through a queue that keeps the interface responsive, then delivered as one ZIP.

Does converting an image reduce its quality?

Converting between lossless formats does not. Converting to a lossy format such as JPG, WebP or AVIF re-encodes the pixels, and some loss is inherent to that — which is what the quality slider is for. The split-view comparison shows you exactly what you are getting.

Why do I have to wait ten seconds before downloading?

Because the site is funded by the ads shown during that break. It is the only thing keeping the tool free for everyone, and disabling your ad blocker is the other half of the deal.

Does it work on a phone?

Yes. The whole interface is responsive, and the conversion runs on the same browser engine, so phone and tablet work identically to desktop.

Do you need an account to use the tools?

No. Ten conversions a day work without signing in. A Google account simply removes the daily cap — there is nothing else behind it.

Why it works

A converter that runs where your files already are

Most image tools upload your file to a server and hand it back. This one never sends anything anywhere — which is faster, free to run, and impossible to leak.

Nothing is ever uploaded

Every pixel is decoded, resized and re-encoded by your own browser through the Canvas API. There is no server holding a copy of your photos, and no queue to wait behind.

Real-time preview

Move any slider and see the result immediately, with a split view to compare against the original. You always know what you are downloading before you download it.

Real image controls

Dimensions, aspect ratio, quality, target file size, brightness, contrast, exposure, highlights, shadows, white balance, vibrance, sharpen and denoise.

Pixel-correct resizing

Large reductions happen in halving steps, close to true box-filtering, then a light unsharp mask restores the crispness interpolation takes away.

Batch everything

Drop up to 20 files, apply one setting to all of them, and download the whole batch as a single ZIP. A bounded queue keeps the page responsive throughout.

Free, with no catch

Ten conversions a day without an account. Sign in with Google when you want unlimited use — no card, no trial, no upsell.

How it works

Three steps, about ten seconds

No account, no queue, no waiting for someone else's server.

1
Drop your images in
Drag and drop, paste from the clipboard, or browse. Whole folders are fine — the converter picks up every image it recognises.
2
Tune the output
Pick a format, set the quality or a target file size, adjust dimensions, and dial in the colour. The preview updates as you type.
3
Download
Save a single file, or grab the whole batch as one ZIP. A ten-second sponsored break comes first — that is what keeps the tool free.

Format support

Every format that matters, in both directions

The output list only shows formats your browser can genuinely encode, so nothing ever fails silently.

Image formats supported for reading and writing by PixelForge
Format	Extensions	MIME type	Status
JPG	jpg jpeg	image/jpeg	Read & write
PNG	png	image/png	Read & write
WebP	webp	image/webp	Read & write
AVIF	avif	image/avif	Read & write
GIF	gif	image/gif	Read & write
BMP	bmp	image/bmp	Read & write
HEIC	heic heif	image/heic	Read (device dependent)
TIFF	tif tiff	image/tiff	Read on some browsers
SVG	svg	image/svg+xml	Read (vector)

HEIC, TIFF, SVG and ICO are listed because your browser may be able to read them. If it cannot, the file is flagged with an explanation rather than failing silently — and the HEIC page has the fastest workarounds for every device.
