Image converter and resizer
Change an image from one format to another, resize it, and squeeze it under a file size you choose — free, with no sign-up and no watermark. JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, ICO, SVG and the HEIC photos an iPhone saves. Everything happens inside this page, on your own device, so your pictures are never uploaded to us or to anyone else.

How to convert an image
-
Choose your images
Drag them onto the box above, or click Choose images. Up to thirty at a time, read straight from your disk into this browser tab.
-
Pick the format and the size
Choose what to convert to. Set a quality, new dimensions or a target file size only if you need them — the defaults are sensible on their own.
-
Convert and save
Press Convert. A single image downloads on its own; a batch can be saved together as one
.zip.
Every format, in both directions
Any input can become any output, so there is no separate page to find for each pair. These are the ones people ask for most:
Formats it reads
- JPG / JPEG — photographs from any camera
- PNG — screenshots, logos, transparency
- WebP — images saved from the web
- AVIF — the newer, smaller web format
- GIF — including animated ones, first frame
- BMP — Windows bitmaps
- TIFF / TIF — scans and print masters
- ICO — existing favicons and icons
- SVG — vector drawings, rasterised
- HEIC / HEIF — iPhone and iPad photos
Formats it writes
- JPG — smallest for photos, opens anywhere
- PNG — lossless, keeps transparency
- WebP — roughly 30% smaller than JPG
- AVIF — smaller again, newer browsers
- GIF — 256 colours, universally supported
- BMP — uncompressed, for older software
- TIFF — lossless, for print and archiving
- ICO — a favicon with every size inside
Common conversions
- HEIC to JPG — iPhone photos for anything else
- PNG to JPG — a screenshot small enough to email
- JPG to PNG — an image to edit without more loss
- WebP to JPG — a download that will not open
- JPG to WebP — a faster-loading website
- PNG to ICO — a favicon for your site
- SVG to PNG — a logo where vectors are not allowed
- TIFF to JPG — a scan small enough to send
Two ways to make an image smaller
"Smaller" means two different things, and mixing them up is why people end up with a blurry picture that is still too big to attach. This tool does both, separately.
Smaller on screen — the dimensions
How many pixels wide and tall the image is. A 12-megapixel phone photo is 4032 × 3024, which is far more than a website, a document or an email needs.
- Fit inside a box — the usual one. Give it 1920 × 1080 and every image comes back no larger than that, each keeping its own shape. Leave one side blank to constrain only the other.
- Fill a box and crop — for thumbnails that must all be the same shape. The image covers the box and the overflow is trimmed from the edges.
- Stretch to an exact size — forces both numbers, and will distort the picture if they do not match its shape.
- Scale by a percentage — half size, quarter size, and so on, whatever each image started at.
Smaller as a file — the kilobytes
How much disk space it takes. This is what an upload form means when it says "maximum 2 MB", and it is only loosely related to the dimensions.
- Tick Aim for a file size, type a number and choose KB, MB or GB.
- The image is encoded several times at different qualities, and the best one that lands under your limit is kept. It takes a second or two longer than a plain conversion.
- If even the lowest useful quality is still too big, the dimensions are reduced as well — and the result says so rather than pretending.
- For PNG, TIFF, BMP and GIF there is no quality setting to turn down, so the size is reached by resizing alone. For a strict limit on a photograph, JPG or WebP will get you much further.
Which format should you choose?
| JPG | Photographs, and anything going to a form that will only take one. Smallest for real-world pictures, no transparency, and every re-save loses a little more detail. |
|---|---|
| PNG | Screenshots, logos, diagrams and anything with transparency or sharp edges. Lossless, so it never degrades — but much larger than JPG for a photograph. |
| WebP | Images on your own website. Around 30% smaller than JPG at the same quality, keeps transparency, and supported by every current browser. |
| AVIF | The smallest of the lot, often half the size of JPG. Newer, so check that whatever has to open it is current. |
| GIF | Flat graphics with few colours, or anywhere that still insists on it. Limited to 256 colours per image, so photographs lose a lot. |
| BMP | Older Windows software and embedded systems that read nothing else. Uncompressed, so the files are very large. |
| TIFF | Print work and archives. Lossless and widely accepted by publishers, scanners and document systems. |
| ICO | A website favicon or a Windows application icon. One file holds 16 to 256 pixel versions so the system can pick the right one. |
Your images stay on your device
The usual way to build an image converter is to accept an upload, process it on a server and send the result back. That means your photographs — your family, your ID scan, your unreleased product shots — sit on a machine you do not control, protected by a retention promise you cannot verify. This page works differently: the code that reads and rewrites your images is downloaded to your browser and runs there. There is no upload endpoint, nothing is logged, and we could not retrieve your pictures if we wanted to.
There is a second privacy win people do not expect. A photograph from a phone carries EXIF metadata: the camera, the date, and often the exact GPS coordinates where it was taken. Converting an image rewrites its pixels and leaves all of that behind, so the file you get out is stripped of it. The rotation recorded in EXIF is read and applied to the pixels first, so your portrait photos do not come out sideways.

ماڻھو جيڪي سوال پڇندا آھن
Is this image converter really free?
Yes. No account, no trial, no watermark and no daily limit. The conversion runs on your own computer, so there is no server bill for us to pass on to you.
Are my photos uploaded to a server?
No. Your images are read by code running in your browser tab and the converted files are built in the same place. Nothing is transmitted, nothing is stored, and we never see your pictures. Load the page, switch your connection off, and the converter still works.
Which image formats can it convert?
It reads JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, ICO, SVG and HEIC/HEIF — the format an iPhone saves photos in. It writes JPG, PNG, WebP, AVIF, GIF, BMP, TIFF and ICO. Any input can go to any output, so PNG to JPG, HEIC to JPG, WebP to PNG, JPG to WebP, SVG to PNG and the rest are all the same two clicks.
How do I make an image a specific file size, like 200 KB or 2 MB?
Tick "Aim for a file size", type the number and pick KB, MB or GB. The converter then encodes your image several times, each at a different quality, and keeps the best one that comes in under your limit. If even the lowest useful quality is still too big, it reduces the dimensions as well and tells you that it did.
Can I resize images at the same time?
Yes, and it is the same pass, so there is no quality lost to converting twice. You can fit an image inside a box — 1920 × 1080, say — fill a box and crop the overflow, stretch to an exact size, or scale everything by a percentage. Leave one side blank in "fit" mode to constrain only the other one.
Can it convert HEIC photos from my iPhone?
Yes. HEIC and HEIF are read and can be converted to JPG, PNG or any other output. Safari and recent versions of macOS read HEIC natively, so nothing extra is downloaded there; on Windows and Android a decoder is fetched the first time you pick a HEIC file, which takes a moment on a slow connection.
How many images can I convert at once?
Thirty per batch, up to 50 MB each. They are converted one after another rather than all at once, which is what keeps memory flat: your device only ever holds one decoded image, whether you queue one file or thirty. When more than one has finished you can download them together as a .zip.
Does converting lose quality?
It depends on the format you choose. PNG, TIFF and BMP are lossless, so the pixels come out exactly as they went in. JPG, WebP and AVIF are lossy: the quality slider decides how much detail is traded for file size, and 80–85% is where most people cannot see the difference. Converting a JPG to another JPG always re-encodes, so keep the quality high if you will edit the file again.
What happens to transparency?
PNG, WebP, AVIF, GIF, TIFF and ICO keep it. JPG and BMP cannot store transparency at all, so transparent areas are filled with a colour you choose — white by default, and the colour picker appears when you select one of those two formats.
What about animated GIFs?
The first frame is converted and the animation is dropped. The file list says "animated: first frame only" as soon as you add one, so you know before you convert rather than after.
Is EXIF data, including GPS location, kept?
No, and that is usually what you want. Re-encoding an image drops every piece of metadata with it: camera model, date, and the GPS coordinates that phone photos carry. The rotation stored in EXIF is applied to the pixels first, so a portrait photo stays the right way up. If you need the metadata preserved, this is the wrong tool.
Can it convert RAW files from my camera?
No. CR2, NEF, ARW, DNG and the other raw formats are not images so much as sensor readings, and each manufacturer does it differently. Export a JPG or TIFF from your camera software first, then convert that.
How do I make a favicon?
Choose ICO as the output. You get a single .ico containing 16, 24, 32, 48, 64, 128 and 256 pixel versions — every size Windows and the browsers ask for — up to the size of your original. A non-square image is padded rather than squashed.
Does it work on a phone?
Yes, on iPhone and Android. Pick images from your camera roll or your files app and the converted copies land in your downloads. The conversion runs off the main thread, so the page stays responsive while it works.
Handling images at scale?
We build image pipelines — upload, resizing, format negotiation and delivery — into web platforms and business systems. If your team is resizing pictures by hand, that is usually a sign something upstream can be automated.
