Convert an Image to the Format You Need
What changes when you convert an image to another format
Convert images between the output formats shown in the format selector, including JPG, PNG, WebP, AVIF, TIFF and ICO. Choose a quality setting where supported and a background color when saving transparency into an opaque format such as JPG. For animated inputs, select a frame or create a contact sheet. Changing the file extension alone does not convert the image.
Cost: Free to use. File size and usage limits apply.
How to convert an image
Add one image
Click Upload an image to convert or drop a file onto the tool: JPG, PNG, WebP, GIF, BMP, ICO, TIFF, TGA, AVIF, HEIC or HEIF, up to 200 MB. Files lists images you uploaded or created in the other image tools, so you can convert a result without downloading it first.
Pick the output format
Click a format card under Output. WebP is selected when the page opens.
Set quality and matte color
Move the Quality slider for JPG or WebP. Change Matte color only if the image has transparent areas and you are converting to JPG or BMP.
Decide what happens to an animation
If the source is animated and the target format holds a single image, choose First frame, Frame at time or Contact sheet under Animation export.
Resize if needed
Switch on Resize during export and enter Width and Height in px. Leave it off to keep the original dimensions.
Convert and download
Click Convert to. When the job has finished, drag the slider across the preview to compare the result with the original, then click Download. The result is also added to Files.
Which output format to choose
Renaming a file does not change its format. The tool writes a new file, and the format you pick decides file size, transparency and whether an animation survives.
WebP (default)
Still images are saved lossy at the Quality you set, with transparency kept, even when the source is a PNG screenshot. Choose PNG when every pixel must stay exact. Animated GIFs stay animated and are encoded losslessly.
JPG
Lossy and without transparency, but it opens in practically every program and on every device. Transparent areas are filled with the Matte color. Every re-save as JPG loses a little more detail, so convert from the best original you have.
PNG
Lossless with full transparency. Text, screenshots, logos and flat colors stay sharp. A photo saved as PNG can be larger than the JPG source; compare the actual file sizes.
AVIF
Lossy at a fixed encoder quality, so there is no Quality slider; transparency is kept. AVIF can be a compact choice for photos, but compare the actual file size and check that the destination software opens it. Some older browsers and image editors do not. It stores no animation.
GIF
Keeps animations but allows at most 256 colors per frame, and each pixel is either fully transparent or fully opaque. Photos show banding or dither patterns.
ICO
Holds one image of at most 256 × 256 px. A larger image is scaled down and centered on a transparent 256 × 256 px square. The file contains a single size, not a set of 16, 32 and 48 px icons.
TIFF, BMP and TGA
Written without compression at about 3 bytes per pixel, or 4 with transparency: a 4000 × 3000 px photo becomes roughly 36 MB. TIFF and TGA keep transparency; BMP uses the Matte color. Pick these only when print, design or game software asks for them.
Settings and when to change them
The preview shows your source image while you adjust the settings. The converted result appears in a before-and-after comparison once the job has finished.
- Quality
- Shown for JPG and WebP only. Range 1–100 %, default 90 %. For JPG and still WebP, lower values can reduce file size and add blocks or smearing around edges and gradients. Try 75–85 % for web photos and inspect the result; start at 90 % or above for further editing. Animated WebP is encoded losslessly, so the slider changes compression effort rather than loss of detail.
- Matte color
- Default white (
#FFFFFF). Only JPG and BMP use it: transparent and semi-transparent pixels are blended onto this color, and it fills the empty border of a fitted resize and the background of a contact sheet. Match it to the background the image will sit on. - Animation export
- Appears when the source is animated and the output format holds one image. First frame (default) exports frame 1. Frame at time exports the frame visible at the Time you set, in seconds from 0 to the end of the animation. Contact sheet lays out every frame in a grid, left to right and top to bottom.
- Columns
- For Contact sheet only: 1–12, default 4. Each cell is as large as the largest frame. Animations with more than 200 frames cannot become a contact sheet, and sheets larger than 8192 px on a side are scaled down.
- Resize during export
- Off by default. Width and Height start at the source's own size and accept 1–8192 px each; scaling uses the Lanczos filter. Enlarging does not add detail. For ICO, values above 256 px are reduced to 256 px.
- Aspect ratio lock
- The lock button between Width and Height is on by default: change one value and the other follows the source's proportions. With the lock off, the image is stretched or squeezed to exactly the size you enter. If the values no longer match the source proportions while the lock is on, the image is fitted inside that box and the rest stays transparent, or takes the Matte color in JPG and BMP.
Formats and limits

- Output formats
- JPG, PNG, WebP, GIF, BMP, ICO, TIFF, TGA, AVIF
- Maximum file size
- 200 MB per image
- Files per job
- 1; earlier uploads and results stay in Files
- Output dimensions
- 1–8192 px per side when resizing; ICO files at most 256 × 256 px
- Animation
- Kept when converting an animated GIF or animated WebP to GIF or WebP. Other targets get one image chosen under Animation export; contact sheets take up to 200 frames.
- Multi-image files
- A multi-page TIFF converts its first page, and a multi-size ICO converts its largest icon. HEIC and HEIF give one image per file, and animated PNG files are converted as a single image.
- Processing
- On our servers with ImageMagick. HEIC and HEIF are decoded with FFmpeg first, and animated WebP output is encoded with FFmpeg. A job can run for up to 15 minutes.
- Watermark
- None
- Storage
- Uploads and results are deleted automatically after 48 hours for guests and after 30 days for free accounts. Paid plans can keep files longer.
Frequently asked questions
Why is the converted file larger than the original?
The target format and source image determine the size. A JPG photo can grow when saved as lossless PNG. TIFF, BMP and TGA are stored uncompressed: about 3 bytes per pixel for 8-bit RGB, or 4 with transparency. JPG and WebP at the default Quality of 90 % can also exceed an already heavily compressed source. For JPG or still WebP, try a lower Quality, compare WebP and AVIF, or use Compress Image and check the resulting bytes.
Does converting a JPG to PNG or TIFF improve the quality?
No. A lossless format keeps the pixels exactly as they are, including the blocks and blur that JPG compression already caused; it only prevents further loss. Converting between lossy formats, for example JPG to WebP, adds a little new loss. To enlarge a small image with more detail, use AI Upscale, which generates detail with an AI model instead of stretching pixels.
What happens to transparent areas?
PNG, WebP, AVIF, TIFF, TGA and ICO keep them. GIF keeps only fully transparent or fully opaque pixels, so anti-aliased edges and drop shadows can look jagged. JPG and BMP cannot store transparency and blend those pixels onto the Matte color, white by default.
Will my animated GIF stay animated?
Yes, if you convert it to GIF or WebP: every frame, the frame timing and the loop setting are kept. Other formats hold one image, chosen under Animation export.
Does the new file keep EXIF data and my location?
PNG, WebP and AVIF can carry over EXIF data, including GPS coordinates; conversion alone does not guarantee removal. To publish a photo without camera data and location, run the result through Compress Image with Strip metadata switched on.
How do I make a favicon or app icon?
Choose ICO. The icon holds one image of up to 256 × 256 px; larger images are scaled down and centered on a transparent square of that size. Crop your logo to a square first with Crop Image so it fills the whole icon instead of leaving empty bands.
